Erm, Van Persie scored one and he actually delivered the ball into the box that Evra/Vidic scored from. So 1 "goal" and one "assist" each. Evra is having a great season in terms of goals scored (for his normal standards at least) but Van Persie is their most clutch player.
Evra gave that superb pass in the box where Van Persie scored the goal. You have to admit that that assist was a crucial one. And if Evra didn't head the ball to Vidic's head, it won't be a goal. The team deserves more credits, their passes to Van Persie and the other forwards are crucial
You said, "two fine assists". The first was fine enough, but the second was more due to him completely misplacing the header than anything else.
I would have told Camacho to find a new team tonight. What a loser. Where I'm from the fans would be waiting for him outside after the game.
