Good defending by Reece James as he hooks the ball away before Claudinho can shoot from a headed flick-on.

Robert Lewandowski v Gerard Pique is going to be fun. The defender wins round one, holding off the big striker as a ball is chipped over the top. The Pole goes down briefly, but there's little chance of a penalty.

Chelsea have had 74.5% of the ball, but neither side has managed a shot yet.

Remo Freuler has given Atalanta an early lead in Villarreal.

Romelu Lukaku tries to control a long ball into the box but can't quite get it down.

Marcos Alonso loses the ball in attack for Chelsea - Ben Chilwell mightn't be too disappointed at that - but Zenit can't make the counter count.

If Barca had an inferiority complex here, there's no evidence of it so far. They've been the side on the front foot, testing Bayern's defence with a couple of crosses.

Boos and whistles for Bayern as they play it around patiently at the back. It'd be astounding if we get another 8-2 like that one played out in front of an empty stadium 13 months ago. But you do fear Barca might be there for the taking for a side as strong as Bayern.

Joshua Kimmich is already in the book, though, for hauling a man back to stop a home attack.

Chelsea are just finding their stride now. Cesar Azpilicueta whips in a cross from deep but can't find Romelu Lukaku.

Good strength by Antonio Rudiger to barge Malcom off the ball and play a long ball down the left wing, but Zenit get it away.

Chelsea play themselves into early trouble - Jesse Lingard style - but Zenit can't take advantage.

Bayern are unbeaten in six games this season under Julian Nagelsmann.

The last time these European giants met, Bayern won 8-2 in the 2019-20 quarter-finals, Barca’s heaviest defeat since 1951.

Barcelona have lost seven matches against Bayern Munich, three more than they have against any other side in Europe (P11 W2 D2 L7).

The last time they met in the group stages was 1998-99. That was one of only three times Barcelona have ever gone out in the groups.

Barcelona have not lost their opening match in a Champions League campaign since... Newcastle United beat them 3-2 at St James' Park in 1997-98.

Tino Asprilla scored a hat-trick that day. As every Newcastle fan I know mentions every time Barcelona come up in conversation.

Chelsea did very well out of the Champions League draw. The holders are in a group with the Euro Club Index's, external lowest ranked second seed (Juventus), lowest ranked third seed (Zenit) and second lowest ranked fourth seed (Malmo). This 'luck of the draw' has boosted Chelsea's chance of progress to the knockout phase from 81% to 92% making them the second most likely team to go through.

Chelsea are given 7.2% chance of winning a second successive Champions League, making them fifth favourites for this year's competition.
