Well I dont think we will get Pazzini or Destro and i dont think Juventus will sell Matri. IT would make no sense to sell Matri who scored 10 goals last season and then buy Pazzini who scored 5 goals in 33 matches. Why would we do that? Does it make any sense? Then again it is Marotta who is making the deals
Trying to make sense
Assuming that our forward line next year will be like this Vucinic , giovinco , quagli , Top striker and The fifth striker .
Sell matri , buy pazzini for a lower amount (it would be genius if he resolves his contract with merda and we get him for 0 , althrough i don't think it will hapen), add the remaining money to fund the TOP . In the end both pazzini and matri when we buy the top will probably be the fourth most likely fifth choice , so only in case of injuries they will have the chance of playing , it would not be wise to keep a player with matri's worth as fifth , even more if the coach doesn't particulary like him .
I also think that pazzini is sghlitly better , althrough there is not much difference between them
