Manuel Almunia - 3
Arsene Wenger's biggest mistake in his life thus far. He's not fit to guard the Arsenal goalpost and always has the tendency to score own-goals.
He was reluctant and his distribution was poor in this game (as always). It's time to offload this ineffective goalkeeper. His mistake might prove costly in the end.
Bacary Sagna - 7.5
He played well for most part and patrolled the right wing in the best possible way. He also ably supported the attack and teed up some good crosses into the box.
Sol Campbell - 6
He was outmuscled and outpaced by Cameron Jerome. You can't expect more from a 35-year-old player. He found himself at the end of a corner only to head the ball over the top of the crossbar.
Alex Song - 7.5
He was one of the better players for Arsenal on the pitch. He kept James McFadden at bay for most part of the game. His tackles were pleasing to the eyes except the one on McFadden, which earned him a yellow card.
Gael Clichy - 7
Played well for most part of the game and combined well with Tomas Rosicky but his crossing wasn't good. Walked on a tight rope after being booked in the early part of the game.
Cesc Fabregas - 5.5
Really poor game by his standards. Craig Gardener's challenge on Fabregas in the first half didn't help, either.
He was uncomfortable after that robust tackle but went on to play the full game with little effect.
His major contribution was a perfect through ball, but Nasri wasted that chance just before Birmingham's late equaliser.
Denilson - 6
Played as the holding-midfielder and did a satisfactory job. His passing was good but couldn't stand up to the rough play and Birmingham players easily dispossessed him.
Abou Diaby - 8.5
Arguably the best Arsenal player on the pitch. He ignited all the attack and dribbled past defenders with ease on a couple of occasion. The referee disallowed his goal for a foul by Fabregas.
Tomas Rosicky - 6.5
A decent game and almost scored with a brilliant strike from long range. His touches and passing skills were commendable.
Nicklas Bendtner - 5
Poor game for this tall striker. He was hardly involved in the game and wasted a good chance to score in the second half from Nasri's cross. He should've done better.
If these indications are anything to go by, then Arsenal are going to struggle with the Dane up front against Barcelona in the midweek fixture at the Emirates.
Theo Walcott - 6
His blistering pace almost gave the lead for Arsenal in the first half. However, his passing and crossing were awful. He wasn't involved in the game much.
Samir Nasri - 8
Came on after the hour-mark and terrorised the Birmingham defense. He was the cutting edge that Arsenal needed in the first half.
Floated in a perfect cross to Bendtner, only to see the Dane make a mess of it (as expected). Later, he broke the deadlocks with a long-range strike perfectly into the far corner.
Andrei Arshavin - 5
Came on for Walcott and did a better job. He created a decent chance for Nasri to score.
Wenger made a mistake by leaving him on the bench, now it seems like both Premier League and Champions League are out of Arsenal's reach.
