Fiorentina have dismissed speculation linking Adrian Mutu and Sebastien Frey with moves away from the club.
Mutu has been in fine form this season and has now scored 25 goals in 18 months at Fiorentina.
Roma are understood to be interested in the Romanian, while there has also been speculation of a possible transfer to Real Madrid.
However, Fiorentina have reiterated their determination to keep hold of Mutu, and have also warned any suitors off Frey.
The Frenchman has been linked with Milan, but Fiorentina director of sport Pantaleo Corvino insists there is no chance of him being let go.
"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."
Asked if there had been any offers, Corvino said: "We too knock on the doors of other clubs for their great players, but then they always say no.
"Everyone tries. I don't know if they did so for our players, but the transfer market is a game in which everybody attempts to get the best pieces for themselves."
Christian Vieri joined Fiorentina in the summer after brief spells at Sampdoria and Atalanta, but his future has yet to be tied up.
Fabio Liverani is in a similar situation, while a number of top clubs, including Liverpool, Tottenham, Atletico Madrid, Juventus and Zenit St Petersburg, are all believed to be interested in Tomas Ujfalusi.
Corvino said: "We have a few situations with Vieri, Tomas Ujfalusi and Fabio Liverani that we will try to face and resolve at the right time."
