We need 7 Points to win. We have West ham then Aston villa then Arsenal. We can win the title at Arsenal if we win 6 points at West ham and Aston Villa-Only 1 POINT NEEDED IN emirates stadium.
I don't know if that is good or not. Yes, Van persie can prove a point to Arsenal supporters for his choice in coming to utd, but he may not celebrate or relish us winning the title as much at emirates as that would be 'disrespectful' etc.
