Mertesacker was caught out by Kebe
GK Wojciech Szczesny (6/10)
Despite the fact that Arsenal managed to concede two goals, Wojciech Szczesny spent the majority of the game relatively untroubled. He couldn't have done much about either goal.
In the case of Adam Le Fondre's strike, I thought Szczesny did well to stand up and not commit himself for as long as he did. Le Fondre, however, showed his fabulous finishing ability to get round the big Pole. It would be churlish to fault Szczesny himself.
DR Bacary Sagna (7/10)
Bacary Sagna is, alongside Mikel Arteta, one of the most consistent and professional players at Arsenal Football Club. This was yet another game in which he put in a very honest shift, topped off by a fantastic cross-field pass in the build-up to Santi Cazorla's first goal.
CB Per Mertesacker (5/10)
Per Mertesacker has been Arsenal's most reliable centre-back this season, but in this game he was caught out by the run of Jimmy Kebe for Reading's second goal.
During that 10-minute period in which the Royals scored twice, Arsenal were wobbling, and Mertesacker looked more like the uncertain figure he occasionally resembled in his first season at Arsenal.
CB Thomas Vermaelen (5/10)
Although untroubled for long periods, Thomas Vermaelen's second-half performance saw some bad habits creep back in to his game. He is occasionally too eager to win the ball early, allowing him to be easily turned.
When Reading turned the screw, he seemed perturbed, which isn't what you're looking for from your captain.
DL Kieran Gibbs (8/10)
For a full-back to pick up two assist in a single game is some achievement. Kieran Gibbs' marauding runs down the left have made him integral to this Arsenal team, and when his partnership with Lukas Podolski on that flank clicks, it can be lethal.
The only reason he doesn't score higher is that it was his misplaced cross-field pass that led directly to Reading's first goal.
