That really was despicable by Nasri. I think a draw would've been a fair result considering the balance of play and how Man City came back in the second half, but equally Van Persie deserved a slice of luck after that amazing shot with his weaker foot that hit the inside post.

Considering Man Utd usually pick up in the Christmas period, it might be very difficult for Man City or Chelsea to catch them now. Only an injury to Van Persie looks like slowing them down.
