Fiorentina sports chief Pantaleo Corvino insists Sebastien Frey and Adrian Mutu will not be leaving.

"We have given these players long-term contracts because we believed in them more than anyone else and before anyone else," Corvino told Sky Italia.

"Now that we have put pen to paper, we have the pleasure of keeping them for a very long time."

Christian Vieri signed in the summer after brief spells at Sampdoria and Atalanta, but his future is yet to be tied up.

"We have a few situations with Vieri, Tomas Ujfalusi and Fabio Liverani that we will try to face and resolve at the right time."
