Manchester United defender Nemanja Vidic had agreed a move to Fiorentina but changed his mind at the last minute, according to Pantaleo Corvino.The Serbian defender called time on his career at Old Trafford earlier this year, confirming a deal with Italian side Inter Milan but former Fiorentina president Corvino has discussed how he almost signed the centre-back in 2006.Vidic who joined United from Russian club Spartak Moscow had agreed terms with the Serie A club but late talks with Sir Alex Ferguson saw him change his mind and move to England.Ferguson countered a problem with the Florence side that saw them have no free non-eu spots in the squad, meaning they had to sell before they signed Vidic.And, Corvino has talked about the change of decision in a recent interview with SkySport.Vidic to Inter? First of all I wish him a great season with the club, but the first thing I will ask is for him to give me back my agreement. We had agreed terms and paid the buy-out clause with Moscow. We had also reached an agreement over his salary but United offered 3-4 times greater than us.
