It had to be Fabregas. Fabregas, who has stalled in the past few games reclaimed his claim to the throne with a brilliant last-ditch solo effort to blast the ball into the net from distance. Walcott then followed up in extra time to square the ball to Adebayor to put the match beyond doubt. Arsenal, the first English team to ever beat AC Milan at the San Siro.
About time. Arsenal dominated the game, only looking exposed in the first 15 minutes when Milan threatened. The ref, appropriately enough, was wearing Milanese colors, making a series of terrible calls against Arsenal. The most egregious was giving Hleb a yellow card for diving, which apparently translates to "falling down under a tackle that took out his legs but none of the ball." Shocking.
At any rate, Arsenal are threw to the last eight. I hope we get another "big team." We seem to do better against the big guns.
