I seriously can't think of a single player coming to the EPL from Seria A and being any good or not considered a flop of the top of my head. Shevchenko, Aquilani, Maccarone, Veron. I'd be wary of signing Vucinic as he's been in Italy so long it could take him awhile to adapt if he ever did at all but for a good low price he might be worth the risk. Didn't he say some rather disrespectful stuff about Tottenham afew seasons ago when we were linked to him?
Vialli, Zola, Di Canio, Di Matteo, Nicola Berti
