I reckon that will just about do us.

Hours before kick-off, chief executive Michael Nicholson said "it was a sad day for Celtic" following Peter Lawwell's decision to step down as chairman at the end of the year.

He had no idea how much sadder it would get for those in green and white.

Dundee United came from behind to claim their first victory over Celtic since 2014, as Wilfried Nancy went a fourth game without a win.

Celtic have now gone four games without a win for the first time 1978.

You can read the match report on the tab beside this one, while the reaction from Tannadice will run long into the night on the BBC Sport Scotland website - and particularly our Celtic page.

Thanks for your company tonight, we go again tomorrow with Aberdeen's final Conference League game.

It's amazing how quickly this has gone pear-shaped.

A tricky few days for Wilfried Nancy, you'd have to say.

For anyone who perhaps isn't on the auld X and was confused by that full-time graphic from Dundee United, Wilfried Nancy was active on the app yesterday - despite saying he was taking a break from it.

The Celtic boss cleared it up pre-match with Jonathan Sutherland...

"My wife was not happy, believe me or not, that my profile picture was in the locker room at Columbus Crew," he told BBC Scotland.

"I wanted to change my WhatsApp picture, as simple as that. It was not a message, I don't want to start a battle.

"I just wanted to change what I had in my WhatsApp."

Wilfried Nancy needed to come in and hit the ground running and he hasn't done that.

What he does need to do is get his team performing.

Sunday [against Aberdeen] is going to be really interesting.

Earlier today, chief executive Michael Nicholson said Celtic's support of Wilfried Nancy is "absolutely solid" as he revealed meetings were held this week to discuss signing targets for January and next season.

More on that here.

As said, it's the first time since 1993 a non-Old Firm club will sit top at Christmas.

Jambos have to go back to 1991 for their last time topping the tree on the big day.

When asked if Celtic is the right club for him, Wilfried Nancy replied: "Come on - I know the situation. Everybody wants to win, me too," he told Sky Sports.

"But I know there is improvement. Context. Just step back, have a look at the context.

"The idea is to see what we can do, what we can do to improve the team, the players and I think I am in a good direction with the players.

"Today you saw we had a good performance. But in three minutes we lost the game. For the moment that's the factual situation.

"I can understand the fans are not happy with me, I want a connection with the fans but that is hard when we don't win."

When a full fanbase turns against a manager, that's the end.

And I don't think we're too far away from that.

Wilfried Nancy has urged Celtic fans to "keep faith" while realising that "it is difficult for them" after four defeats in a row.

"I can understand," the manager tells BBC Scotland. "I am a human being and disappointed and the connection with the fans is important for me.

"But we had clear chances and we have to help the players with that. We have to work on certain things."

Asked if he regretted changing the system succesful for interim manager Martin O'Neill, he adds: "Martin plays a certain way and me I want to see something that we can win games for the future.

"At the moment, it is not that, but I can see we are improving."

"For sure, it's difficult for the club and the players, the staff and myself. But again, it's difficult for me to talk," Wilfried Nancy tells Sky Sports.

"We've lost four games in a row, but today we were close to winning the game. It's the direction we have to keep going in, and we have to be stronger to avoid conceding these kinds of goals."

In among these Wilfried Nancy quotes, a wee reminder Sportscene is on in five minutes on BBC One Scotland.

Tune it to not only watch Zac Sapsford's superb winner, but Nancy's interview.

"Step back, have a look at the context," Wilfried Nancy tells Luke Shanley of Sky Sports.

Haven't we heard something similar this season from elsewhere?

Celtic manager Wilfried Nancy blames "three minutes" for his side's defeat.

"We lost the game in three minutes - two set-pieces that we conceded," he tells BBC Scotland.

"Maybe the second one was offside before the corner.

"I think we did a good job - I think we had a good performance with all the opportunities we had in the first half.

"If we score the two or three tap ins we had, it would have been a different score."

I see you, Dundee United admin...

Celtic are "on the right track" according to a "confident" Wilfried Nancy.

Full quotes coming soon, but the Frenchman is being handed a lengthy grilling.

Jim Goodwin hopes United can kick on from this victory.

"At half-time, we thought we were going to get opportunites," the manager tells BBC Scotland.

"We had two or three half chances in the first half.

"It has been a long time since we beat Celtic in front of our own supporters, it was 2014 the last time, and that's one for them.

"We are not getting carried away. We are not happy with our league position, but that gives us a lot of confidence."

Dundee United manager Jim Goodwin admits his side carried a bit of luck but pointed to a half-time substitution for turning the game.

"It's a massive three points for us," he tells BBC Scotland.

"Given the run of form we've been in up until tonight, it was about trying to turn these draws into victories and we managed to do that.

"It was very much a game of two halves. Celtic were really good in the first half and started really brightly.

"They caused a lot of problems with the ball in behind and we found ourselves getting caught in that mid zone of the pitch and ultimately that's where the goal came from.

"I don't think we've carried a lot of luck during the campaign, but I think we carried that in the first half as Celtic could have been out of sight.

"We were able to make an adjustment at half time and bring a little more pace into it and the game was mainly played in Celtic's territory before seeing out the game brilliantly."

Wilfried Nancy is speaking now... "we played a good game," he says.

Let's hear from Jim Goodwin in the meantime while we scribble Nancy's stuff down.
