Robert Lewandowski has assisted two Champions League goals in a game for the first time.
Chelsea 0-2 Bayern Munich
Double change for Chelsea. Tammy Abraham and Willian replace Olivier Giroud and Ross Barkley.

It's schoolboy from Chelsea. You expected the net to ripple there seeming he already has two goals.
Chelsea 0-2 Bayern Munich
It's almost a Serge Gnabry hat-trick for Bayern but he lashes a shot over the bar.
Antoine Griezmann (57 mins)
Barcelona are level and it's as simple as you like. Nelson Semedo gets in behind Napoli's defence and his low cross is swept home by Antoine Griezmann in the centre.

Dare I say it, did Robert Lewandowski make his run a little bit too early?

Chelsea have been on the back foot for much of the night and this last 16 tie is surely all but over unless there is a dramatic turnaround.
Bayern have played some lovely football and how former Arsenal man Serge Gnabry loves London - four in the group stage at Spurs now two here.
Chelsea 0-2 Bayern Munich
Chelsea are on the ropes now. This could end up a big scoreline. Not 7-2 big, mind. Kingsley Coman flies down the right and crosses to Robert Lewandowski. It's behind the big striker, who tries a scorpion kick but can't make contact.
Napoli 1-0 Barcelona
Now Barcelona make a change as Arthur replaces Ivan Rakitic.
Napoli 1-0 Barcelona
Dries Mertens won't be breaking the Napoli goalscoring record tonight. He's injured and is replaced by Arkadiusz Milik.

Imagine how many goals Serge Gnabry would score if he played for a London club...

Same combination, same sort of link-up. It's a more difficult finish. A devastating couple of minutes for the Germans.
Serge Gnabry (54 mins)
Six goals in two visits to London this season for Serge Gnabry. It's another Gnabry-Robert Lewandowski one-two.
They interchange the ball near the halway line and Gnabry speeds away before blasting in a shot.
Remember when we said Serge Gnabry has scored five goals in London this season?
Chelsea 0-1 Bayern Munich
It was Serge Gnabry who started the move for the goal too. Cesar Azpilicueta's slip was costly as Gnabry sped away from him before picking out Lewandowski and then getting on the end of the Pole's cross.
Chelsea 0-1 Bayern Munich
All five of Serge Gnabry's Champions League goals this season have come in London (four at Spurs, one tonight).
Napoli 1-0 Barcelona
Barca midfielder Sergio Busquets will miss the second leg after being booked for a foul on Dries Mertens.

You have to say absolutely devastating from Munich. It's so quick. We say what a great goalscorer Robert Lewandowski is, but it's build-up play of the highest quality. He cuts it back beautifully. It's wonderful, wonderful link-up play. It's a deserved lead.
Serge Gnabry (51 mins)
Serge Gnabry scores in London for the fifth time this season. Robert Lewandowski gets the ball in the box and crosses when everyone is expecting a shot. Gnabry smashes it past Willy Caballero from about 10 yards out.

Jorginho puts his hands on the referee which is a huge risk. He was protesting it should be a booking to Joshua Kimmich.
