Liverpool 2-1 Atletico Madrid

Carry on like that and a new contract won't be a problem, Alexis.
That is such a good hit from Alexis Mac Allister. Anfield is bouncing.
Alexis Mac Allister (50 mins)
BOOM.
The ball is bundling around the box and it bounces out for Alexis Mac Allister to HAMMER into the bottom corner, giving Jan Oblak no chance.
Will he get his new contract now?

Oh, Bradley. That was the moment for him.
Liverpool's counter attack is stunning as Florian Wirtz prods it through for Barcola but he slots it the wrong side of the post.
Has to score.
Napoli 0-0 Arsenal
Napoli start the second half on the front foot and Billy Gilmour runs onto a loose ball before rifling the ball at goal. Saved by David Raya - but the referee spotted something so it wouldn't have counted anyway.

Frightening how open Liverpool are playing. A little lucky to be level at the break. Full backs a serious worry, in both directions!

Liverpool 1-1 Atletico Madrid
Liverpool work the corner short to Alexis Mac Allister at an angle. He lifts it in first time and Ronald Araujo directs a header the wrong side of the post.
Decent little routine, that.
Liverpool 1-1 Atletico Madrid
Florian Wirtz finds the run of Bradley Barcola on the right and he uses his pace to win Liverpool a very early corner.

Nedum Onuoha
Former Manchester City defender on MOTD: UEFA Champions League
Odegaard's passing has been superb so far. If someone is going to create something in the second half, it is probably going to be him.
You can hear more from Onuoha on MOTD: Uefa Champions League at 22:40 BST on BBC One and the BBC Sport website and app.

Napoli 0-0 Arsenal
Napoli change keepers at half-time. Alex Meret picked up a knock in the first half and Vanja Milinkovic-Savic is taking his place.

Stephen Warnock
Former Liverpool defender on MOTD: UEFA Champions League
We have not seen much from Liverpool's wingers yet and Andoni Iraola might have to change things to get them more into the game.
Barcola was brought in for exactly this kind of situation, against a team who are happy to sit in like Atletico, to take on defenders one-on-one, but so far he has not really had the chance to do that down the right.
On the other flank, Rio Ngumoha has had a few attempts at running at Llorente with the ball, but has not had much success yet.

HT: Napoli 0-0 Arsenal
Bukayo Saka has had five shots so far. On record (since 2003-04), only Thierry Henry has had more in the first half of a Champions League match for Arsenal (six v CSKA Moscow in November 2006).

Cristian Romero won more duels than any other player in the first half, with six out of six.

Saka looks short of confidence. Should be burying those chances.

I think Ngumoha and Wirtz have been very good battling to get the ball back in the Atletico half. Neither are big lads but they are causing issues. As usual with Liverpool, they have created a chaotic game with both teams very capable but looking messy.

HT: Napoli 0-0 Arsenal
Arsenal's 13 shots is their most on record (since 2003-04) in the first half of a Champions League away game
HT: PSG 3-0 Slovan Bratislava
It's safe to say PSG are cruising to an opening game win in the Champions League here.
The question is, will Ousmane Dembele get his hat-trick?

I think the Liverpool fans will feel aggrieved for many different reasons. Decisions that have gone against them and the way the referee has been inconsistent.
HT: Sporting 1-1 Galatasaray
Level at the break in Lisbon. Galatasaray have had nearly all the chances in this game and led through Goncalo Inacio's own goal before Geny Catamo levelled.
Napoli 0-0 Arsenal
Arsenal have had the better chances of the first half but have not found a breakthrough yet.
