GK Lukasz Fabianski (8/10)
On a night of surprises, there was no greater surprise than the performance of Lukasz Fabianski. It was the Pole's first start for Arsenal in more than a year, and he looked like a changed man: solid, dependable and confident.
Wojciech Szczesny was left out of the game due to the mental toll of his exertions in the Premier League. Fabianski's performance will make Arsene Wenger wonder which of his two Polish goalkeepers to opt for in the crucial clash with Swansea this weekend.
DR Carl Jenkinson (8/10)
Carl Jenkinson's storming performance was typified when he raced back against the fleet-footed Arjen Robben to confidently rob the Dutchman of the ball and single-handedly prevent a Bayern Munich goal.
Jenkinson's performance was one of his best of the season, matching up to his excellent early-season form. Bacary Sagna is due to return soon from injury, but he may find it hard to displace the in-form Englishman.
CB Per Mertesacker (8/10)
Per Mertesacker looked typically composed at the heart of the Arsenal defence. He is a natural organiser and marshalled Arsenal's most impressive defensive display in months.
After the nightmare of the first leg, the big German will have been particularly pleased to put in such a competent display in his homeland.
CB Laurent Koscielny (9/10)
Selected ahead of skipper Thomas Vermaelen, Laurent Koscielny responded with one of his best performances of the season. He was quick into the tackle, aggressive in the air and even scored a fantastic headed goal.
With Thomas Vermaelen on the sidelines for this game, Koscielny is in the driving seat for the spot alongside Mertesacker. The captain faces a real fight to reclaim his spot.
DL Kieran Gibbs (7/10)
Arsenal fans are accustomed to long lay-offs for their injured stars, so it was great to see Kieran Gibbs back in an Arsenal shirt earlier than expected. He immediately looked an assured member of the Arsenal back line, although he wasn't able to influence Arsenal's attacking game as much as he would have liked.
Gibbs now faces a fascinating battle with Nacho Monreal to occupy the left back slot. On the strength of this performance, Gibbs has to be the front-runner.
