The start is so important for Tottenham. If they want this fanbase to get behind the team then they will need to start on the front foot.

Kylian Mbappe runs onto a long ball over the top by Marquinhos. The defenders can't catch him but Yann Sommer races off his line to get there first. Mbappe's momentum takes him into Sommer and Bayern have a free-kick.

Theo Hernandez is put under immediate pressure by Dejan Kulusevski but the Spurs forward has fouled him.

The first long ball over the top to Kylian Mbappe. He controls it and finds Lionel Messi but the move ends in Achraf Hakimi's overhit cross.

Off we go in London. Huge game for Spurs. The atmosphere is brilliant.

No real pattern to this game yet. Nothing close to a chance bar that Kylian Mbappe shot. Neither team really on top.

Dayot Upamecano cuts out Lionel Messi's through ball. It's a front two for PSG now Neymar is crocked.

Tottenham's players are lined up in the tunnel, ready to go. They're waiting for AC Milan.

We could be a little later than 20:10 for kick-off but it's not long now.

An early Bayern goal would make things a bit more comfortable for the German champions. Kingsley Coman's cross is cleared and Fabian Ruiz boots the ball into touch.

This season AC Milan have been terrible away from home. They have won five and lost six and their wins have been against teams struggling in the league.

It feels like away from home they have been able to find their feet, they are just not a team you would fear right now.

First chance lands to PSG legend Kylian Mbappe but his shot from a tight angle is saved by Yann Sommer, who joined Bayern in January after Manuel Neuer's skiing accident.

Only Cristiano Ronaldo (85) and Lionel Messi (77) have made more appearances in the Champions League knockout rounds than Bayern's Thomas Muller (65).

This is Messi's 150th start in a Champions League game. He is the third player to reach this milestone, after Cristiano Ronaldo (178) and Iker Casillas (176).

A potentially classic Champions League last 16 tie is under way.

Tottenham need a response after a bad start to the month.

They lost to Sheffield United in the FA Cup and then at Wolves in the Premier League.

They lost the first leg of this tie in Milan 1-0 last month too and need to win to keep their only realistic hopes of a trophy alive.

Since beating Spurs in the first leg, Milan have picked up two wins from three, losing 1-0 to Fiorentina on Saturday.

Losing Franck Kessie in midfield meant AC Milan lost a lot on a tactical level then they have had several injuries that forced them to change the way they play recently.

They thought they bought well in the transfer market but as it came to be, they weren't really great additions to the squad.

I don't know if you can stop Kylian Mbappe. PSG have plenty of ball players out there.

Bayern can play a lot deeper but if you give a lot of space to Mbappe it could be a long evening for them.

Son Heung-min said Spurs' exit from the FA Cup was "painful" and they hope to put it right in this competition.

"To be a good season we have to do our best things. We are still in the Champions League and fighting for the top four," said Son.

"Everyone dreams of playing in the Champions League. Words are not enough - we have to prepare and have a clear plan.

"If we turn it around it could change the season and give us a little confidence and boost."

Paris St-Germain try to play out from the back but they don't have the patterns of play to be able to build out. They aren't really press resistant with only Marco Veratti only able to do it.

Bayern will come out and press and the higher they win the ball the more dangerous they will be.

The Milan fans packed out their section pretty much as soon as they were allowed into the stadium. Both teams are out and warming up and know what they need to do to progress.
