City threaten for the first time as Sergio Aguero stabs a pass through for David Silva to chase. Erik Sviatchenko is alive to the danger.

City are rocking. The pace that Celtic have started at is incredible. Will they be able to keep it up? I said early on about scoring early and pressing on regardless. They are doing just that.

The Celtic bombardment continues with Scott Sinclair driving into the box from the left and his low cut-back is eventually hacked clear by a frazzled City defence.

City just can't handle these Celtic free-kicks. Erik Sviatchenko gets his head on another good delivery from Scott Sinclair and Moussa Dembele is on it in a flash, with a smart shot on the turn. Claudio Bravo needs to bat it away.

Wow. Just wow. The best thing about the goal is that Celtic have started so well, but it's a technical thing done by the manager. They knew Man City were going to keep a high line at the free-kick, try to play offside. That is straight off the training ground.

And we're off! City playing in a weird orange and purple kit, Celtic in their traditional hoops.

That stirring Champions League anthem is playing again at Celtic Park after an absence of almost three years. The noise from the stands is ridiculous.

Celtic Park is rocking! The scarves are aloft and You'll Never Walk Alone is belting out. 

Not long to go now...

Celtic manager Brendan Rodgers has elected for Craig Gordon in goal, the Scot having replaced Dutchman Dorus de Vries at half-time during Saturday's 6-1 defeat of Kilmarnock.

Up front, Moussa Dembele retains his place as the main striker with fit-again Leigh Griffiths on the bench.

Rodgers talking to BT Sport: "Dorus obviously came off injured at the weekend, maybe he could've played. You don't need to take the risk. Craig's an outstanding goalkeeper.

"Moussa's on great form."

Dembele has 10 goals for the season, six in the last five games.

Celtic boss Brendan Rodgers talking at Tuesday's media conference:

"We know we have to bring our A game to have any chance and that is something hopefully we can do. 

"The reality is if they bring their A game and we bring ours, they win. But we know we have to make it as uncomfortable as we can for them. 

"We have a respect for their qualities and their game but we have to ensure we are super-committed into our way of working and we know we have players that can give them a problem. 

I have watched them in the last four or five seasons and they have always had an outstanding group of players, winning leagues and cups. But the level of play has gone up since Pep has come in. 

"The intensity has gone up and they are a team working with one idea and they are a hard team to contain. We know it is going to be a difficult night but we know it is going to be a difficult night for them."

Hibernian manager on BBC Radio Scotland

You have to give credit to both managers the way they have reinvigorated the teams.

The football City are playing just now is spectacular. Celtic need to be aggressive. If you stand off a Guardiola team, they will pick you apart.

Celtic have a few City insiders in their ranks, which might help. Kolo Toure and Scott Sinclair are former players and winger Patrick Roberts, on the bench tonight, is halfway through an 18-month loan.

City defender Aleksandar Kolarov spoke admiringly of the trio at yesterday's media conference.

"I played with all of them and spent some years with them at City," he explained.

"Kolo is an experienced player and has had a great career in England. Scott didn't play a lot at City but I know him well and he's a great player. 

"Patrick is a young guy with a great future. His strength is in the one-on-ones. He is quick and if you give him the space and time he can hurt you."

Of all the years I've been watching games here, I can't remember Celtic ever playing for a point. It's not in their DNA. Brendan Rodgers is a Celtic man at heart and knows the fans want intelligent attempts to attack. Play for a point? I don't think so.  

Celtic skipper Scott Brown talking yesterday:

"It's about getting touch tight. We sat off Barcelona and admired them more than anything, letting them play and show what good players can do to you if you sit off them. We need to get our bodies in and try to win the battles all over the park.

"We're going to have to work as a team, we're going to have to composed on the ball and take our chances if we get them. 

"Guardiola has come in and brought a different style for them which seems to be working in the Premier League so far. We've got a gaffer who's tried a different style for us and it's been working in the Premiership.

"It will be a good proper game of football, both teams like to get the ball down and play it. It's always going to be hard playing against good players, but we need to show our qualities and step the game up a little bit."

City boss Pep Guardiola isn't reading too much into Celtic's hammering against his former club.

"Many, many teams suffer the same as what happened in Barcelona," he said yesterday. "You cannot imagine how many goals Barcelona can score in five minutes but tomorrow for 92/93/94 minutes they will be focused so it will be completely different. 

"It is not easy. I saw the game against Rangers here, how intensive it was. It was completely different to the way they played in Barcelona, which was more passive. Against Rangers it was so aggressive, high pressing, that is the game we are going to expect from them."

Heavy rain delayed Manchester City's 4-0 win over Borussia Monchengladbach by 24 hours on match-day one and the visitors have brought more bad weather with them to Glasgow.

It's a soggy night in the East End of the city as the players go through their warm-up routines.

A couple of former Celtic players have expressed concern for their old side.

"Their best hope is to start the game well at a high tempo and try to not let Manchester City get into a rhythm, and get control of the ball," John Collins told BBC Radio Five live.

"But it's a tough ask - many teams in England have tried this season and failed."

Meanwhile, Dion Dublin told Focus Forum: "Celtic won't have much of the ball. What City need to be aware of is the amazing atmosphere at Celtic Park but they will overcome it and they'll pass and pass and pass. Celtic need to be careful to keep the numbers down because I think it could be a big score."
