Again Manchester City gift possession to Monaco as Tiemoue Bakayoko intercepts a pass to Kevin de Bruyne and immediately finds Valerie Germain, who shoots over from distance.

Kylian Mbappe is a real thorn in the Manchester City defence at the moment. 

The 18-year-old has the ball in the net again as he bends his run to break free of the defence and meet a pass from midfield but he is offside. Just.

We haven't really seen the Manchester City front five link up as yet. In fact, Sergio Aguero is looking a lonely figure in the Monaco half as the quartet of Raheem Sterling, Kevin de Bruyne, David Silva and Leroy Sane drop back to fill the space in midfield and try to halt these Monaco attacks.

Another goal for Monaco means they will go through on away goals if Manchester City fail to score.

At the moment, the visitors are having to cope with some heavy pressure.

Paul Collins‏: Man City's defence is criminally terrible! That includes overrated golden boy John Stones.

We're well aware that Manchester City's defence can be suspect at times but it needs to tighten up and tighten up quickly. 

Fernandinho gave the ball away under little pressure for that first Kylian Mbappe chance and then no-one picked up the forward for his goal.

Now Bacary Sagna gets himself an unnecessary early yellow card with a reckless challenge. 

City need to keep their heads.

It is far too easy for Monaco.

Benjamin Mendy went past two men so easily but it was a brilliant finish from Kevin Mbappe. He is lightning fast and full of confidence.

We have a game on.

Well, we didn't have long to wait for a goal!

Monaco issue a warning when Kylian Mbappe's shot was palmed away by Willy Caballero but the teenager doesn't miss with his next chance. 

Benjamin Mendy, a real livewire so far, is allowed to break into the area and, after his initial cross is blocked, Bernando Silva swiftly picks out Mbappe to stab home.

I have played here a couple of times, the atmosphere has not been as good as this, you can feel the edge.

What we have seen so far is how important Fernandinho will be tonight. He has already dropped in to make a back three for Manchester City.

City are going to try and dominate possession.

Now we see play quickly move towards the City goal after an attack by Pep Guardiola's side a Danijel Subasic catches Kevin de Bruyne's cross and immediately bowls the ball up field. 

Benjamin Mendy has space to cross on the left but his effort is cleared. 

Early chance for Bayer in Spain. Kevin Volland turns his marker on the edge of the box but pulls his shot just a yard past the far post.

A reminder - the German side need at least three goals tonight. That was nearly one of them. 

Already you can feel we're going to be watching the ball quickly move from one end of the pitch to the other as Manchester City charge away after Djibril Sidibe's cross is cleared to Leroy Sane, who quickly finds David Silva but the midfielder's attempt to pick out Kevin de Bruyne just inside the Monaco half is cut out.

Bring on the goals!

I just hope this match lives up to the expectations.

Here's a reminder of the line-ups. I wonder how many of these names will be on the scoresheet come full-time?

Monaco: Subasic, Sidibe, Raggi, Jemerson, Mendy, Fabinho, Bakayoko, Lemar, Bernardo Silva, Germain, Mbappe-Lottin. Subs: De Sanctis, Jorge, Dirar, Joao Moutinho, Irvin Cardona, Irvin Cardona, Diallo, Toure. 

Man City: Caballero, Sagna, Stones, Clichy, Kolarov, Sane, Fernandinho, Silva, De Bruyne, Aguero, Sterling. Subs: Bravo, Zabaleta, Jesus Navas, Delph, Otamendi, Toure, Iheanacho. 

Referee: Gianluca Rocchi (Italy)

The two teams are in the tunnel. Kevin de Bruyne looks down the line of Monaco players before the referee leads them out.

It's a lively atmosphere at the Stade Louis II. The fans are expecting to be entertained tonight.

Manchester City

Manchester City boss Pep Guardiola tells BT Sport: "We want a guy with a left foot on the left side, they are quick on the counter attacks so Aleksandar Kolarov comes back in.

"We want to win, we will attack and without the ball we will have to defend. Our plan is perfect but we will see. If you do not score away, you have little chance to go through.

Can the teams play another way? "I don't think so. We will try to attack, try to avoid a counter-attack. They HAVE to score to go through.

On 100th game as manager in Europe: "Not bad, I am happy. Already 100? I am happy to be with a lot of my colleagues and managers and hopefully we can celebrate tonight."

Monaco have won only one of six Champions League ties where they had lost the first leg by a two-goal margin, but what a game that solitary win was.

It was back in 2004 when Monaco met Real Madrid in the quarter-finals and the Spanish side were in command after winning the first leg 4-2.

Raul then opened the scoring in the return leg at Monaco to make it 5-2 to Real on aggregate but the French side hit back as two goals from Ludovic Giuly and a Fernando Morientes strike sent Monaco through on away goals.

I wouldn't rule out similar drama tonight...
