You do know that you can see this thing from two different angles?
Milan.. If there is anything they'd pay for its a striker
Real... van Persie would walk into their starting lineup, he's better than Benzema and Higauin
Barca.. They have money and like to do fancy signings. van Persie can also play on a flank, especially if its in Barcelona where you basically not defined by one position
ManU.. They only have Rooney, why not add RVP?
City.. Hey, its City. They have money and they are the favorites to land him right now
Bayern..meh..
PSG.. They have money and this would be a prestigous signing for them. They need it. Would play Lavezzi and RVP while offering RVP some crazy amount of money he can't say no to.
Which brings us to Juventus.. They can't offer him the salary he wants and thats something a player of RVP's age values highly. Also, signing an expensive 28 year old striker doesn't go well with Marotta's philosophy.
See how I turned it around? But sure, I do agree we are interested and an alternative, but question if RVP wants Serie A and the smaller amount of money we're limited to.
