2210: OK one and all, that is just about it from me. What have we learnt tonight? That today may or may not be Boxing Day, dependent on where you are in the world. That crisis is a noun. That a lot of people think cross-cum-shot is a spelling error. That Arsenal can beat the big boys. And that there are no signs of Chelsea coming out of their current slump. Thanks for reading. Jonathan Stevenson will be your maestro of Premier League magic on Tuesday.

Liam, Bradford, via text: "I'm more concerned for Carlo's future than our season. A double-winning, former Champions League winning manager doesn't suddenly become a bad manager over the space of a few weeks. We should stick with him! And really should NOT have sacked Ray Wilkins!! "

Aaron, Kingston, via text: "I want to give Carlo the time to turn this around. However, we are in serious danger of missing out on next years CL. I think we'll be seeing Guus come January."

Arsenal goalscorer Theo Walcott: "It is just a fantastic result for us. We pressed them really, really well as a team."

2203: Hmm, crisis is a noun. How about, as lozza_b_23 on twitter suggested, catastrophic, pants, rubbish, nightmarish, terrible.

2202: Chelsea supporters - how concerned are you? And what remedial work would you like to see done in the January transfer market?

Simon, Lincoln, via text: "Lets not sensationalise please; Chelsea have been woeful recently and have been beaten by smaller sides than Arsenal recently, what other result did people expect?"
Wise and sensible words Simon. Very mature. With your sage shrewdness you obviously had quite a lot on Arsenal to win?

2156: Just six points for Chelsea from their last eight games. What sort of adjective does that warrant? Crisis? Probably. How much time left for Carlo Ancelotti? I'm going to start a Big Sam campaign. he deserves one of the really big clubs.

powerdel on 606: "Wonder how many Bolton fans would have believed you if you told them that if they win their next game against Chelsea, they go above Chelsea."

Chief football writer Phil McNultyat the Emirates: "Arsene Wenger claimed victory for his side would provide a psychological lift to Arsenal in the title race - and they will surely take great confidence from the manner of this impressive victory. Chelsea, in contrast, continue to suffer and the golden form of the early days of the season seems an age away."

2153: 27 December 2010 - the day Arsenal made a psychological breakthrough?

2150: Another lovely through ball from Jack Wilshere, but it has just too much on it for Marouane Chamakh.

2148: Chelsea swing another free-kick into the area and chaos ensues. John Terry's initial header is poor, Didier Drogba's shot on the rebound is blocked and although the ball eventually finds the net, Gael Kakuta's effort is ruled out for offside. Four minutes of injury time.

2145: On comes Tomas Rosicky for Arsenal, replacing Cesc Fabregas. Tick tock, Arsenal heading for three points. Three minutes remaining. Temperature must have dropped, Rosicky has gloves on.

Caboose001 on 606: "Wonder how many Bolton fans would have believed you if you said Bolton would be two points behind Chelsea at the halfway stage...?"

2142: Didier Drogba has a great scoring record against Arsenal, but he isn't having the best of times tonight. He fires a free-kick over the crossbar.

GraymeadYNWA on 606: "I still cannot find the last time Arsenal threw away a 3 goal lead. My first thought was the 4-4 wth Spurs, but they were never 3 up in that one, and I have gone all the way back to 2002 looking for one. I don't know why Arsenal fans are so worried."

2140: Cesc Fabregas fouled by Ramires. Into the last 10 minutes and it is looking for all the world as though Arsenal are heading for a much-needed win against one of the big boys.

2138: It really should be four for Arsenal after Abou Diaby is superbly picked out by Jack Wilshere but he insists on shooting with his right foot when he should strike it with his left and the chance is wasted. Still, it is far best than the effort from Ramires shortly afterwards. High and wide.

canchaz on 606: "As a W.Ham supporter, I find it highly hilarious to read an Arsenal suporter going into panic mode because they give up one goal, whilst scoring three. We'd give our shirts to have that kind of worry."

2136: Chelsea really are struggling to pull clear of Bolton, who are two points behind the London side.

LiveForFooty on 606: "Arsenal should just play with 5 in midfield, slow the tempo of the game down and pass it around Chelsea to take the sting out of the game."

2133: Corner for Chelsea, swung in by Frank Lampard and headed clear by Abou Diaby. Another Gunners substitution as Marouane Chamakh replaces Robin van Persie.

2131: There are 18 minutes of normal time left and Theo Walcott makes way for Abou Diaby. A negative move by Arsene Wenger or shrewdly protecting his team's lead?

Witty_Username on 606: "Oh my days, if we lose this I will blame the goalkeeper 100% and Wenger also 100%. All Arsenal needs to do is keep a clean sheet, how hard can it be. We should buy Casillas in the transfer window."

2125: Cesc Fabregas in the book for a foul on Michael Essien. Chelsea still pushing for another goal but that leaves them exposed to the counter attack. Arsenal strike at pace and Samir Nasri almost scores but Petr Cech manages to save his weak effort.

2125: Technical issue - sorted! If you are missing some Arsenal goal descriptions, please hit refresh. Urgently.

Chief football writer Phil McNultyat the Emirates: Arsenal manager Arsene Wenger is clearly furious with his players for conceding so cheaply after taking that three-goal lead. Didier Drogba now needs to channel his frustrations, illustrated by a furious exchange with John Terry after Theo Walcott's goal, into leading the fightback.

2120: Chelsea working up a head of steam here. The ball breaks to Didier Drogba, whose cross-cum-shot is blocked.

2119: Jose Bosingwa on for Paulo Ferreira, who kisses his team-mate as he leaves the field. Will that inspire him?

2117: Woah. A little bit of housekeeping I've not told you about. Frank Lampard has been booked for a late tackle and Gael Kakuta is on for Florent Malouda.

Chelsea goal: Didier Drogba swings a free-kick into the area and Branislav Ivanovic rises above everyone else to head home.

Gangsta Agger on 606: "At this rate Chelsea could be struggling for a top 4 finish. Time for Roman to bring out the cheque book. Dzeko, David Luiz, Gary Cahill etc. Good luck though competing with City in the transfer market! Still though, it could be worse.... You could be supporting my lot!"

Arsenal goal: Arsenal winger Theo Walcott catches Chelsea midfielder Florent Malouda in possession and the ball breaks to Cesc Fabregas. The Gunners skipper plays in Walcott with a wonderfully weighted pass and the winger clinically slots it beyond Petr Cech.

Arsenal goal: Chelsea are masters of their own downfall. They are caught in possession in defence but Michael Essien appears to have retrieved the situation by forcefully winning back the ball. Alas, it breaks to Theo Walcott, who is clean through on goal. With Petr Cech closing him down, he selflessly squares the ball to Cesc Fabregas, who tucks it into an empty net.

2107: Arsenal win their second corner of the half. No sign of a serious response from Chelsea thus far.

2105: For all those speculating about Carlo Ancelotti's future - might I remind you that one Big Sam Allardyce is out of work.

Gunneruni on 606: "I know Chelsea will score two goals in the second half. Fabianski error not far away!"

2103: Cannot quite work out who was more anonymous in the opening half - Frank Lampard or Michael Essien.

2103: The match resumes. One change for Chelsea, Ramires replaces Jon Obi Mikel.

tommythetank on 606: "The big question now is: How can Chelsea secure a CL place? That's the reality if they play like this."

Liz, Highbury, via text: "My flatmate bought me an Arsenal diary, Arsenal egg cup, Arsenal calculator and Arsenal tic tacs. Best Christmas ever."
Getting better by the minute, I imagine.

Anon via text: "Rafa Benitez to take over from Carlo Ancelotti?"
Never. Won't happen.

2055: Bring back Ray, all is forgiven.

2053: In all the excitement I forgot to mention that Robin van Persie was booked in the opening half. Soz. Chelsea have been disappointing. I almost feel like capping-up disappointing, just for extra emphasis.

2051: HALF-TIME Arsenal 1-0 Chelsea
Phil McNulty's HT snap-shot: "Arsenal have the advantage they craved - and deserved - through Alex Song on the stroke of half-time. Chelsea need to show more urgency and ambition after the break."

joe_white_22 on 606: "Is that the goal that sacks Carlo Ancelotti?"

Arsenal goal:Alex Song plays the ball to Jack Wilshere, who knocks it into a congested area. Cesc Fabregas latches on to the pass but appears to be fouled by Paul Ferreira and the ball breaks to Song, who slots home with a cool low finish.

2044: A poor run can dent the confidence of even the very best. Is it me or do Chelsea lack a little of the bullying qualities that we see from them at their very best?

2042: Inches from the opening goal. Petr Cech is at full stretch to brilliantly tip a looping effort from Samir Nasri over the crossbar. Cracking effort, cracking save.

2030: Into the book goes Chelsea's Salomon Kalou for a high challenge on Gael Clichy. Theo Walcott glides past the statuesque John Terry as though he does not exist but Petr Cech is able to bundle the ball out for a corner.

2038: Here we go again. Pass, pass, pass, pass, probe, probe, probe. Not enough pace and incision from the home team to hurt....oh, space opens up for Theo Walcott down the right but John Terry heads the winger's cross clear.

2036: Beautiful. Almost. Sparkling one-touch football exposes a chink in the Chelsea backline but Robin van Persie then drills his shot welllllllll over from a tight angle.

2034: Hmm, starting to reach that 'this game needs a goal' stage. Better possession and ambition from the home team over the last 10 minutes. Chelsea could do with a little spell in possession.

From ChelseaFC_Fan on Twitter: "Impressed with Mark Clattenburg. He is controlling this match, not allowing his decisions to be made for him by players. "
The clue is in the name, perhaps.

2030: Chelsea defender Ashley Cole rather naughtily kicks the ball away after fouling Theo Walcott and is booked for his miscreant endeavours.

2029: Arsenal started well but Chelsea have a good defensive shape and it seems to me like there are more and more of those moments when the home team are enjoying a lot of possession without causing enough problems. We've seen that before against the big boys.

2026: Very frustrating touch from Theo Walcott, who is briefly one-on-one with John Terry in a wide area but the winger is betrayed by poor control and the defender snuffs out any danger.

2024: The first save of any note as Petr Cech stops a Samir Nasri free-kick.

2022: Big appeals for a penalty by Arsenal as Robin van Persie goes down after tangling with Florent Malouda. Referee Mark Clattenburg correctly waves play on.

Czechmate on 606: "This is what always happens in this fixture, Arsenal start well and put pressure on, but then they make a mistake Chelsea get a corner or free kick which they score from and Arsenal go behind and start to panic and don't get going again"

Chief football writer Phil McNultyat the Emirates: "Arsenal have started well - but the warning signs are already there from Chelsea's Didier Drogba as he pulls a shot just wide and then sees a header deflected over. John Terry fortunate to escape a booking for a foul on Robin van Persie, despite the best efforts of Arsenal captain Cesc Fabregas to persuade referee Mark Clattenburg to produce the yellow card."

2018: Clumsy, very clumsy, from John Terry, as he tangles with Johan Djourou. The two men are battling to connect with a teasing free-kick from Robin van Persie. It isn't a penalty - there isn't enough contact - but Terry needs to be careful.

2017: Didier Drogba looking dangerous again as he attempts to meet a cross at the near post. Johan Djourou manages to scramble the ball clear for a corner.

What_Would_Dev_Do on 606: "When I was at school, many moons ago, snoods were all the rage for the girls, but they came up over your head. They were a bit like those plastic rain caps old ladies wore that you bought in a bag, but made of wool and not old shower curtains. I hereby recommend plastic rain caps that tie under the chin for all Premiership footballers. Only when it rains though, otherwise they would look somewhat foolish."

2014: Chelsea boss Carlo Ancelotti really does like his black trench coat. He looks like an extra from bad 70s movie. We've not seen too much of Frank Lampard so far. John Terry loses the ball and deliberately drags down Robin van Persie. Should be booked. Isn't.

2010: Bakari Sagna floats a teasing cross towards Theo Walcott, who cannot quite make contact. A very open 10 minutes so far.

2008: Don't reckon the home team should be doing that! Didier Drogba is given the space and time to close in on goal before shooting from 20 yards. The Ivorian skews his shot wide.

2007: Arsenal have undoubtedly settled quickly and look to have much more intent than we saw at Manchester United in their previous fixture. Robin van Persie is very close to connecting with a looping high ball into the Chelsea area. Not a bad chance.

2004: Some sweet passing football from Arsenal but the killer decisive ball from Cesc Fabregas to Robin van Persie catches the Dutchman in an offside position. Close mind.

2003: Cannot see a single snood. Oh, Samir Nasri has let the side down. A few crunching early tackles, just to set the tone.

2000: The match has started. It is so (relatively) warm the big Did has taken his gloves off.

1958: In answer to Mo - no, Frank Lampard is not wearing a snood. Then again, it is a lot warmer tonight in London than previous days.

1956: The comeback starts - apparently The Radio Times described Sunday as Boxing Day - and in Britain it is always the day after 25 December (although not always elsewhere). The players are in the tunnel. Nervous energy aplenty.

Tom via text: "My Polish mother-in-law bought me an Arka Gdynia bib for Christmas. So she wants grandkids, and she wants them in Poland. Subtlety not one of the Poles' strengths."

1952: According to Infostrada Sports, this is the last time Arsenal host a fellow London club this season. Only Fulham have taken fewer points (one) from London derbies this season than Arsenal's six.

1950: A lot of chat about the relative strengths of the two subs benches, particularly the lack of depth on Chelsea's. Let me give it to you again: Turnbull, Ramires, Bosingwa, Van Aanholt, Bruma, Kakuta, McEachran. I'm not seeing a lot of proven goal-scoring prowess.

Glyn, Kensal Rise, via text: "Blast! Fridge-freezer has broken down. Food in plastic boxes in the garden! On the plus side, six days worth of turkey gone in bin! Plenty of room temperature red wine to help ease the pain of watching Drogba scoring against us again. Hope VP scores more!"
Cannot agree. Six days worth of turkey sounds magnificent. As for room temperature red - how else would you want it?

1942: Hmm, should have waited longer before eating the second turkey bap. Gone big way too early.

Arsenal manager Arsene Wenger: "It is a big game but the players sometimes think they have to be exceptional in big games - sometimes they need to focus on doing the basics right."

lancer01 on 606: "My girlfriend also bought me an Arsenal shirt - and the mug. She's so sweet I haven't got the heart to tell I'm a Chelsea supporter."
I'd work up the heart before that situation gets badly out of hand.

1937: Arsenal have not defeated Chelsea since November 2008, having lost their last five encounters. The Gunners were poor at Old Trafford in their last game and I think they have something to prove this evening. I've been surprised by the amount of people I have met tipping the home team.

From RCS1984 on Twitter: "No, Paul, Boxing Day is not the first WORKDAY but the first WEEKDAY after Christmas Day. RS Caracas, Venezuela."
Honestly, I wish I'd never mentioned it!

Jack Deacon, Worthing, via text: "As a Chelsea fan I ordinarily look forward to playing Arsenal every year; beating them always establishes that we mean business. I'm a tad worried this time though, I can see us overly relying on Didier & Lamps, neither of whom are completely fit and allowing Arsenal a goal through a set piece late on. Maybe it's just the nerves kicking in. "
Nervy Chelsea fans - a sign of the times?

BermudaPool on 606: "Wife bought me some LFC chocolate coins. Can I redeem them for Xabi Alonso?"

From xFied on Twitter: "Any Manchester United fan will enjoy today's match more than any fan of either club, whatever be the outcome."

1924: Hmm, seems like today might be Boxing Day. Lots of people telling me it is the first workday after Christmas. Having said that, Sunday is a day of work in my world.

Chief football writer Phil McNultyat the Emirates:Arsenal manager Arsene Wenger has handed a weighty responsibility to Robin van Persie in attack against Chelsea, with Andrey Arshavin and Marouane Chamakh only on the bench. Lukasz Fabianski returns in goal and captain Cesc Fabregas starts. Johan Djorou partners Laurent Koscielny in central defence with Sebastien Squillaci on the bench.
Chelsea, as expected, give Frank Lampard his first start in four months in a powerful-looking line-up, with Didier Drogba the spearhead. Nicolas Anelka is missing, however, with a knee injury.

1920: Nicolas Anelka is not in the Chelsea squad as Carlo Ancelotti makes two changes from the team that drew at Tottenham.

TEAMS ARSENAL V CHELSEA:
Arsenal: Fabianski, Sagna, Koscielny, Djourou, Clichy, Song, Fabregas, Wilshere, Walcott, van Persie, Nasri. Subs: Szczesny, Diaby, Rosicky, Squillaci, Arshavin, Chamakh, Bendtner.
Chelsea: Cech, Ferreira, Ivanovic, Terry, Cole, Essien, Mikel, Lampard, Kalou, Drogba, Malouda. Subs: Turnbull, Ramires, Bosingwa, Van Aanholt, Bruma, Kakuta, McEachran.

1919: So, Arsenal versus Chelsea - just what does this mean, exactly? It is third against fourth, with the Gunners able to move up to second if they win, while victory for their opponents will elevate them to third. Arsenal lost their last fixture, away at Manchester United on 13 December, and have been beaten three times already at home this season. Chelsea have taken just six points from their last seven games - their worst run of form since 1998. Pick the bones out of that lot.

Rob, Arsenal fan, London via text: "My girlfriend got me an Arsenal toothbrush, Arsenal shower scrubber thing, Arsenal pen and an Arsenal mug with my name on it."
She really loves you, I think.

1911: Some people claiming on 606 that today is Boxing Day. That cannot be right - can it?

1910: Contact. Please. All thoughts on this evening's fixture would be greatly appreciated, but I'd also like to know about any strange football-related presents that arrived in Santa's sack this Christmas. You know the sort of thing, life-size photo of Kevin Davies, Wycombe Wanderers ear muffs. Tweet me @paul__fletcher,text me via 81111 or get yourselves on over to 606. Hit me.

1908: Some early Arsenal team news. Lukasz Fabianski starts in goal, Cesc Fabregas also plays from the beginning while Robin van Persie replaces Marouane Chamakh up front.

Chief football writer Phil McNultyat the Emirates: "Arsene Wenger admits victory against Chelsea would provide a 'psychological boost' as Arsenal attempt to improve a dismal record against their Premier League title rivals. In their last 11 games against Chelsea and Manchester United in all competitions, they have lost 10 and drawn one. As a footnote, Arsene Wenger uses his programme notes to warn Arsenal fans "not to expect miracles" in the January transfer window."

1905: There is something about Didier Droba and the sight of an Arsenal back four. The rampaging Ivorian has not only scored both his team's goals in their last two top-flight fixtures but has found the net a remarkable 13 times against the Gunners in 13 fixtures. Not entirely surprising, he opened the scoring in October's 2-0 win and has been identified by Gunners boss Arsene Wenger as the man his team must keep quiet .

1901: By the way - just where are we with the leftovers situation at the moment? I've opted for a double turkey bun strategy today. Brown sauce on one, salad cream (crazy, I know) on the other. Both have been scoffed already. As has the turkey leg. Bit greedy.

1900: Now then. Does day-after-Boxing Day football entertainment ever come bigger than Arsenal versus Chelsea at the Emirates? Doubt it. Anything more exciting and it might be simply too much for some people. And I would not like to think what that means for units who are by now heavily laden with turkey.
