Nedum Onuoha
Former Man City defender on MOTD: UEFA Champions League

It's a little surprising to see Arsenal so open.

The way Bayern have tried to play at times has led to Arsenal being caught out and being stretched defensively, when we are used to them being so solid, or getting numbers back straight away.

If Bayern's decision making or final ball was better then Arsenal would be behind at half-time but I am sure Mikel Arteta will speak about it at the break and we might see his side being a bit more cautious in the second half, because clearly Bayern are ready for them to attack, and have got a plan for it.

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.

Viking's Jesper Daland had a header blocked from a corner just before half-time and that was their first effort of the game.

Aston Villa should be making it three wins from three in the Champions League, barring a second-half collapse.

Club Brugge 1-0 Lens

Inter Milan 0-0 Shakhtar Donetsk

Real Betis 0-0 Feyenoord

Sporting CP 1-1 Lask

Half time and this is a great watch.

Arsenal have been aggressive and played well.

It's a great moment for Eze to score after the recent criticism too but the Gunners will be worrying about how bad the injury to Saka injury is.

And Harry Kane, wow. Some of the passes this half have been incredible. What a player.

What a chance for Vini Jnr who also takes a punt and strikes the ball outside the box. Not a bad effort at all.

Emiliano Buendia's 20-yard curling shot is deflected behind by a Viking head. That's his sixth shot of the first half.

All square at the break.

Into three minutes of stoppage time.

A howler from Maarten Vandevoordt really who let a simple ball squirm through his legs to allow Bernardo Silva to score into an empty net.

Bernardo Silva trickles the ball into the back of the net after the Leipzig keeper loses control of it and gets his first goal for Real Madrid. That'll be the easiest goal he scores in his career.

Serge Gnabry goes for goal from distance and the shot is deflected behind for a corner. I think Gnabry made the wrong choice, however, as Bayern were attacking three versus two. He had options.

Viking yet to have a shot. They've had one touch in Villa's box.

Another huge chance for Leipzig as Raum goes one on one with Courtois. Courtois stands tall and blocks his shot.

Big save.

Viking are getting really frustrated now. Emiliano Buendia passes the ball and Joe Bell just pushes him over from behind to give away a needless free-kick.

This is end-to-end now as Harry Kane sees his shot blocked before Arsenal break quickly and Eberechi Eze's cross is deflected behind for a corner. The delivery is flicked on but Riccardo Calafiori stabs his shot the wrong side of the post.

Alysson is getting booed when he gets the ball, presumbaly from the visiting Viking fans.

What a chance for Bellingham. He strikes the ball from outside the box with huge power but it goes over the crossbar. Good effort.
