Here come some Milan changes. On comes Charles de Ketelaere - a £35m summer signing that has failed to live up to the billing so far. The other new arrival is Junior Messias.

Pape Sarr has definitely done enough here to warrant further first-team starts. His shot from range lacks precision and is an easy save for Ciprian Tatarusanu.

Fifth meeting between the two. Spurs unbeaten in the previous four, winning two and drawing two, but trailing here by a goal to nil.

But throughout the night I've always felt that Spurs might be able to get something from this game.

Milan try to manage the game with some keep-ball but they're not capable under pressure from Spurs. It sets the visitors off on an attack that ends with Richarlison seeing an angled shot blocked.

For the first time tonight, we see Mbappe close to his best. He streaks away from the Bayern defence, however his attempted chipped finish is blocked by Yann Sommer.

The ball runs free to Lionel Messi, however his shot is blocked. It eventually falls into the path of Mbappe again, who puts it in the net.

However, he was clearly stood in an offside position and the goal is ruled out.

The first thing he does is brilliant, the second thing he does gives the ball away. That's the inconsistency that he's got, but he is a pleasure to watch.

Richarlison is sent on to try and spark something for Spurs. Off goes fellow forward Dejan Kulusevski, who has offered little.

We're heading into the last 20 minutes.

Will Milan feel that 1-0 is enough with which to go to Tottenham? Do Spurs have the bravery to commit more men forward in search of parity while risking being punished on the break?

I can't really recall a worthwhile chance for either of the sides in this half.

Harry Kane has got the bit between his teeth now, he's angry. He wants to get that goal. He want to get Kjaer back.

It must be a nightmare playing up front with Rafael Leao. You never know when the ball is going to come to you. He holds on to the ball as Milan attack and Olivier Giroud's good movement is wasted.

Eventually, the French striker does get the ball for a cross that is chested behind by a man in white. Thankfully for Spurs, the corner comes to nothing.

Another waste of a good opening!

Clement Lenglet does really well to beat two men on the left but with Harry Kane waiting in the middle his low ball is cut out.

It's a very bitty game and I think that's what Milan want. They want to break up the game as much as possible, hope that they can get Leao on the ball now and again to run at the defenders.

You've got to remember Romero is on a yellow card, so if he gets him one-on-one, he's going to go by him, not even a shadow of a doubt.

At the moment, I think Milan would probably take the 1-0.

Spurs continue to press the Milan defence, but a decent final ball continues to elude them.

Scott: Sarr has been our best player tonight.

Ed: Absolutely baffling how little Sarr has played for Spurs this season. He's looked a class act on the rare occasions he has been on the pitch.

Bayern should be out of sight, and while Donnarumma must take some blame for the opener he has now kept his side in this tie.

The Italian makes a fine near post stop from Choupo-Moting, then a flying save to deny Benjamin Pavard from the resulting corner.

Meanwhile, Mbappe is clearly not fully fit. The usually lightning forward can barely break into a jog.

Eric Dier is into the book now, and it is a costly foul on Olivier Giroud. He is now out of the second leg.

I'll be honest, it shouldn't be a yellow. He had a hold of Giroud, sure, but enough to warrant a booking? No chance.

The Milan keeper still has an issue with his ankle but he has the easiest job in the world to come out and claim the corner unchallenged.

Tottenham are finding gaps. Son Heung-min is given the ball on the right but his cross is blocked behind for a corner.
