One of the da Silva twins really ought to shave their heads to make recognition easier. Fabio da Silva (probably) make space down the left flank and swung in a glorious cross over a sleeping Arsenal defence. Neither Kieran Gibbs nor Laurent Koscielny paid much attention to the ball, allowing Fabio's doppelganger Rafael to nip in and get his head to the ball six yards out. Unfortunately for Manchester United, Rafael isn't much of a finisher and his attempt flew well over Manuel Almunia's crossbar. He really should have scored there - the ball was at a perfect height and he was under something approximating zero pressure from the defenders.
Meanwhile, Patrice Evra has laid in an unpleasant tackle of Samir Nasri, which sent the French winger to ground and prompted a nice little rant about how much the announcer hates him for being a whiner (I paraphrased that). Nasri is fine, of course, but he's well within his rights to fall over when he gets kicked in the ankle while running at full speed. Most of Arsenal's best work is coming down the right side, and Evra's already responding to that with some cynical tackles. It wouldn't be much of a surprise to see the left-back booked at some point in the match.
