Brilliant run by Jamal Musiala before he feeds Eric Maxim Choupo-Moting. The Bayern strriker goes down as the home fans shout for a penalty but it's not given.

Then Joshua Kimmich's shot hits Choupo-Moting.

PSG's first attack of the second half, some nice Vitinha play in the box and Kylian Mbappe's shot is blocked.

Nordi Mukiele is only the second PSG substitute to leave the pitch in a Champions League game after Ezequiel Lavezzi against Porto in October 2012. Lavezzi lasted eight mintues before being injured.

Former Tottenham striker Peter Crouch on BT Sport: "It feels like Spurs are 1-0 up and are seeing the game out. Milan have got so much time to pick their passes."

Sums it up well.

The second half begins. PSG have 45 minutes to save their European season.

What's happened here?

PSG bring on 17-year-old centre-back El Chadaille Bitshiabu for Nordi Mukiele.

Mukiele only replaced the injured Marquinhos in the 36th minute. He must have an injury himself.

Dave J L Eldridge: Romero and Lenglet being 'out' for the next game is wholly irrelevant. There will be no next game based on this type of performance. Zero creativity from Spurs.

Jamal Musiala is just class. The way he moves and dribbles. It feels like he is the guy [for Bayern] if anything is going to happen.

An enormous second-half coming up for Tottenham. They have been miles off it, they have been really tame and tepid against an AC Milan team that haven't travelled well this season.

They still have hope but they need to start taking the game to Milan and gambling and risking.

A few boos at the whistle. It's not been a good half. AC Milan look comfortable with their 1-0 aggregate lead. Tottenham haven't offered anything.

We're strolling to half-time. Milan have a throw-in which is comfortably dealt with.

Bayern have been very mature with Leon Goretzka and Dayot Upamecano really diligent. Lionel Messi has not had any space. Bayern have really stifled him.

PSG have had the best chances without ever feeling in control of the game.

A good battle developing between Malick Thiaw and Harry Kane. AC Milan manager Stefano Pioli keeps reminding Thiaw to stay close to Kane.

Ivan Perisic gets his head on a cross from Dejan Kulusevski but it's very comfortable for the keeper.

Spurs just cannot quite lay a glove on AC Milan at the moment. No lack of effort but not quite the penetration as yet. One or two anxious noises around Tottenham Hotspur Stadium.

Bayern Munich remain the only side yet to concede a first-half goal in the Champions League this season.

Things going to plan for Julian Nagelsmann's side so far.

Paul: When Kane and Son are at their best together one comes deep and the other runs ahead of them so the passer has someone to try play in on goal. Both are coming deep here and it doesn’t work.

Nicholas Walker: Spurs just don't have enough top players to play the Jose/Conte way. We may only get two or three goal chances playing like this and we haven't got the quality to take them.

Dejan Kulusevski is late on Olivier Giroud and Milan have a free-kick inside their own half.

Son Heung-min has barely been involved. He receives a pass from Ben Davies deep inside his own half.

Around 10 minutes to go in this first half and Spurs haven't looked like scoring.

So far, so good for Bayern Munich.

PSG have 45 minutes left to keep their Champions League dream alive.
