That is a chance! It falls to the wrong man, both on a finishing scale and a pronunciation scale, as Dortmund defender Sokratis Papastathopoulos stabs a shot wide. Per Mertesacker had not cleared the corner.

Liverpool left-back Alberto Moreno goes on another long run forward - remember his goal at Spurs the other week? - but this time the final ball is lacking. He looks a find though.

Per Mertesacker has been targeted by Dortmund as they keep running at him, Kevin Grosskreutz is the latest to take the BFG on but the German stalwart waits perfectly before sliding in and nicking the ball away. Bobby Moore-esque.

Arsenal have seen out the first 10 minutes, but that's all they have done. No attacking threat yet from the Gunners.

First goal in tonight's Champions League games goes to Andre Villas-Boas's Zenit as Hulk slots home to put the Russian side ahead at Benfica.

Ludogorets have a crafty plan tonight as their kit is exactly the same colour as the Anfield pitch. It's basically camouflage.

"I think that is the correct decision - there was no contact at all between Mikel Arteta and Henrikh Mkhitaryan, and that yellow card is spot on. He dangled his leg somewhat, but no contact came his way."

Is that a penalty?! No! Referee Oleg Benquerenca books Henrikh Mkhitaryan for a dive as he goes to ground after cutting inside Mikel Arteta, and it's a good call too.

Arteta left a leg dangling out there but he pulled it away before the Armenian hit the deck. Arsenal look ragged at the back though.

Raheem Sterling carries his early season form into the Champions League, skinning his man out wide before being pole-axed by Aleksandar Aleksandrov. So tough they named him twice.

"Dortmund away will be Arsenal's stiffest test in this group. Galatasaray away in Istanbul is always tough, but if the Gunners get a point tonight they should be happy. Mind you, it's been a good start from Dortmund, and Hector Bellerin has already given the ball away, dallying on it..."

Dortmund make the better start, high tempo, high pressing. Vorsprung durch Technik.

"After a typically spine-tingling rendition of You'll Never Walk Alone, the Liverpool fans on the Kop held up white cards depicting the five European Cup trophies the club have won against a red backdrop. Then the iconic Champions League music played out over Anfield for the first time in five years as the teams lined up, followed by a deafening roar. Quite a buzz in the air here as we get under way."

Incidentally, BBC Sport readers today voted You'll Never Walk Alone the best matchday song in football. Watch our video of the top eight here.

"I went to Dortmund as a Wrexham schoolboy to watch a game - I stood on their Kop and what colour, what noise. It was an amazing experience as a teenage player."

The Dortmund "Kop" stands an amazing 25,000 people for league games. They convert it to seating for the Champions League, though...

Referee Matej Jug has left his shorts at home and has had to borrow a pair of grey strides of questionable heritage. We've all been there, nobody likes a trip to the lost property cupboard. He could book Mamadou Sakho for an early lunge but elects for just a stern word.

And game on in Germany too. Arsenal in a fetching blue-on-blue number.

Under way at Anfield...

Former Arsenal and Borussia Dortmund goalkeeper Jens Lehmann: "Defending is more about organisation and less about particular players, who are all sometimes unavailable. Steve Bould is a good defensive coach, so I don't think Arsenal will suffer as long as their offensive players commit more to their defensive duties.

"As for Mesut Ozil, his price tag is not his fault. When he first came to England he started really well, but he's had a winter without a break and then a long, long competition at the World Cup. So he is still trying to find his level this season.

"The fans at Dortmund create an incredible atmosphere; I experienced that myself, when I played there before my move to Arsenal."

Daily Mirror football correspondent John Cross:, external Not saying Klopp is popular here, but before teams come out, his face appears on big screen and announcer gets the crowd to chant his name.

As long as that's all he lays down John. Keep those nerves in check - Arsenal are out at the frankly magnificent looking Westfalenstadion. They call it 'the yellow wall' - because they all wear yellow.

"Young Hector Bellerin is probably having kittens in that dressing room right now, but he needs to go out there and lay a marker down and demonstrate he's good enough to be in this Arsenal team."
