• Celtic beat Utrecht to reach Europa League knockout play-off
• Rangers end European campaign with defeat in Porto

We'll be back across the weekend. G'night.

More from Celtic boss Martin O'Neill on transfers: "We know we need to supplement the squad. We need a wee bit of quality to help, particularly with the extra games now.

"To get another European night at Celtic Park, I don't think it will do us any harm, if we get the players in which I hope we will do.

"It's nice to be in the draw. Whether we're good enough to continue is another issue."

On links to Fares Ghedjemis and Damir Redzic: "I don't know about a percentage [of how likely they are to sign].

"It could be [one rather than both]. There's progress today on certain things. I don't want to be cryptic, but I would hate to say something was certain and it fell away."

Celtic will face either Stuttgart or Ferencvaros in the Europa League knockout play-off round. The winner of that progresses to the last 16.

The draw takes place tomorrow at 12:00 GMT. The first leg is at Celtic Park on 19 February, with the second leg the week later.

Interim Celtic manager Martin O'Neill: "Delighted with the result. Performance for most parts was really terrific. Our pressing was terrific and as a consequence, we got ourselves a couple of goals in front.

"Not that you're ever coasting, but we were doing splendidly. Then they get a goal back, it unnerves you a little bit and they got the second goal and you're beginning to get a wee bit concerned because I thought we were flagging a bit. [Auston] Trusty comes up with a great header and we deserved to win the game.

"You would have got long odds on us qualifying after four games. Great credit to the players. They worked tirelessly. I said to them before the game, last Thursday's performance was magnificent, the performance in Feyenoord was great, so you don't want that to count for nothing. We won and so we're in the next stage.

"I was concerned because we didn't make that many changes after Sunday and I don't think you can constantly press for 90 minutes. There are stages then where you have to sit back. We allow them in for their second goal and that put us on the back foot.

"We win and it's just nice to get through. Winning breeds confidence.

"We are definitely making progress [on transfers], there's no question about that."

It's back to Premiership duty for both Old Firm clubs in this captivating Scottish top-flight season.

Rangers travel to Hibs on Sunday (14:00 GMT) before Celtic welcome Falkirk an hour later.

Benjamin Nygren has 20 goal contributions across all competitions for Celtic this season (14 goals, six assists), the most by any Scottish Premiership player.

Billy Dodds
Former Rangers striker & coach on BBC Sportsound

[Findlay Curtis] has a fantastic attitude to go with his technical ability. His attitude is to die for. He would be a good addition [for Kilmarnock]. It's important he gets minutes. He's been involved for Rangers - 21 games - but it's important he plays full games.

The Sportsound pundits are having a discussion about Rangers youngster Findlay Curtis.

He's been linked with a loan move to Kilmarnock this window, and we happen to have Killie assistant - and former Rangers coach - Billy Dodds on our coverage tonight...

Rangers head coach Danny Rohl tells TNT Sports:"We started well, we were on the front foot in the first 15 minutes and we played well, very brave.

"The two goals after 1-1 were too easy, this moment was the killer. They controlled the game more in the first half and we missed some moments in their half. We have to be brave there.

"Second half, we tried. We played with courage, some good football, but all in all it's a defeat.

"For me, it's about a process. I compare this to my first game in Bergen - I see a big difference.

"You need that extra quality, that extra final pass and that we need to work on.

"In the last two weeks, there's a reason why Findlay [Curtis] got more minutes - he's deserved it. We had a good talk with him two weeks ago, and since then there's been big progress in his development.

"It is great to see this, how brave he is. It's important that at his age he gets a lot of minutes.

"I see Manny [Fernandez] with a good performance, John [Souttar] and Nasser [Djiga] the same. We have a lot of good options in defence.

"I see in the last four games a big step forward."

Thanks to Benjamin Nygren’s sixth-minute strike, Nick Viergever’s 10th-minute own goal and Arne Engels’s 19th-minute penalty, Celtic registered their fastest 3-0 lead in any major European match.

Interim Celtic manager Martin O'Neill tells TNT Sports: "I think over the past couple of weeks we've shown great resilience. We didn't make many changes so they've gone again. We're in the hat.

"The players have done brilliantly. I'm just so glad the win at Feyenoord and [the draw] last Thursday in Bologna counted for something."

On potential transfers, O'Neill adds: "We're making progress and I think we can move it along now in the next couple days.

"It's not been easy. Not just for us, for other clubs too, but perhaps Celtic fans think it's just us. We're trying to do some work and we think we can do it.

"I can never guarantee anything, I don't think anyone can, but we're very hopeful."

Stay right there, Celtic fans.

We've got post-match reaction from Martin O'Neill incoming.

He's, obviously, asked about transfers...

Meanwhile, Celtic captain Callum McGregor started his 66th game in major European competition for Celtic tonight.

Celtic fans, who do you want next?

Thumbs up for Robbie Keane's Ferencvaros, thumbs down for Stuttgart.

Celtic will face either Stuttgart or Ferencvaros in the Europa League knockout play-off round. The winner of that progresses to the last 16.

The draw takes place tomorrow at 12:00 GMT. The first leg is at Celtic Park on 19 February, with the second leg the week later.

So Rangers end their Europa League campaign eliminated in bottom 12.

Celtic progress as the 21st-placed team, but who will they play next?

Let's see...

Celtic captain Callum McGregor tells TNT Sports: "We knew the objective was to win the game and get through to the play-off round.

"When the pressure was on we managed to deliver results. The mentality in the group has been amazing, the boys have been hungry to dig ourselves out of the hole we were in.

"For the first 25-30 minutes I thought we were really good."

On potential January additions, McGregor adds: "We trust the club to get the players the manager and the staff want."

No further goals in the second half, but this scoreline never really looked like it was in too much doubt.

Rangers failed to trouble Diogo Costa in the Porto goal too often, while the hosts took their foot off the gas.

Ultimately, the damage was done in 14 first-half minutes, when Porto scored three goals to rule out Djeidi Gassama's first-half header and put themselves in a very commanding position.
