Either way a move for Van Persie wouldn't make sense. He isn't a wide man and isn't quick enough to be one and centrally Messi has 72 goals this season. Villanova may be his own man with his own principles but he'd be extremely brave to modify Messi's role to accommodate Van Persie.
They've suffered from Villa's absence, his goals from out wide haven't been replaced by Pedro, Tello, Fabregas or anyone else who Pep wanted to plug that gap.
In fact, Juan Mata or GAreth Bale is right up there to help out on flank attack.
DOn't forget..Barca has yet to bid for Rooney..
