GK Wojciech Szczesny (6/10)
The Arsenal keeper could have, and probably would have had a shutout in this match had his defense not fallen asleep twice in the second half. He made the one save that he was expected to, and short of mangling a high cross after the interval, the Pole had very little to do.
He had every right to verbally assault his teammates after his pair of concessions, and should feel confident about his performance going into the weekend game against Wigan.
LB Kieran Gibbs (8/10)
What a performance from Kieran Gibbs. The England international played well defensively, blocking a shot in the 29th minute, and he did even better going forward. He harried the Reading right side all evening, crossing perfectly for Lukas Podolski's goal, and Santi Cazorla's second.
He provided a consistent outlet for the Arsenal midfield in the middle and final third of the pitch, and dovetailed superbly with Podolski all night. Many of Arsenal's best games have coincided with Gibbs being in the starting lineup, and based on Monday night's performance, it was easy to see why. His only blemish was the giveaway that led to Reading's first goal.
CB Thomas Vermaelen (6.0/10)
The Belgian's spotty play continues.
He did well to clear a certain goal in the 28th minute, and also made a terrific last-man tackle in the 90th. Offsetting this was a lack of communication with Mikel Arteta and dubious marking that led to Reading's second goal, which was inexcusable.
If the Gunners had been up against someone other than a last place side playing their worst football of the season, Thomas Vermaelen may have been exposed to a greater degree. The match was a microcosm of the Belgian's season, with moments of excellence offset by instances of confusion.
The Verminator remains frustratingly at-large.
CB Per Mertesacker (7.0/10)
Per Mertesacker continued his excellent run of form, maintaining excellent positioning throughout the match, and completing 90 percent of his passes. For all of the rightful criticism that the towering German international endured during his maiden campaign with the Gunners last season, he has probably been Arsenal's most consistent player since the beginning of the current season.
RB Bacary Sagna (7.5/10)
Carl Jenkinson hardly deserved to lose his starting spot on the right side of defense, especially since his form earned the youngster his first England cap. Bacary Sagna's performance, however, demonstrated exactly why the position is his to lose.
The hard-working French international completed 93 percent of his passes on the night, and 71 overall, chalking up three tackles along the way. He did not play in quite as advanced a position as Gibbs did on the opposite side, which perhaps led to Alex Oxlade-Chamberlain having a relatively quiet night when compared to his teammates.
Nonetheless, the defensive side of Sagna's game was near-faultless, with the right-back at the top of his game despite two broken legs in the past year.
