If you scour team sports over the globe, is van Persie the best player out there simply carrying a team? I am not sure but if this Milan-Arsenal game (replay) is any kind of indicator, and it sure seems consistent with their play this season, then he single-handedly is probably the source of 2/3 of their wins this year. Not sure I've seen another team that is *that* unbalanced.
On a side note, their defense is just bad... I've never heard an announcer say "he's a good kid but he doesn't belong at this level or even EPL" regarding Djourou. Oh well, I am sure Arsene will sell him for a 12-yo prodigy in venezuela.
