The referee was not terrible. RVP got a deserved yellow on Sanga, and Cleverly got a yellow. BOTH players (wilshere and cleverly) were warned after bad challenges they made after their yellow, and Fergie made the right choice in subbing Cleverly off. Maybe if Wenger wasn't so slow he would've also subbed Wilshere off. The Penalty? It was a clear Penalty, I don't care if the ball was going for his face, the rules are no handballs, he's paid what 100k plus a week or whatever? I'd take a ball to the face each weekend if I was getting paid 400 quid a month ffs.
Whatever, you didn't deserve the win. Your first shot on target came in the 92nd minute, and apart from Carzola's goal, your attacking players were nowhere to be seen.
