Fiorentina sports chief Pantaleo Corvino says coach Cesare Prandelli will be in charge next season.
Prandelli continues to be linked with Juventus.
But Corvino said: "Prandelli will stay at Fiorentina also next year. The club has been very clear on this argument.
"I challenge anyone to show that we have ever put the future of our Coach in doubt. Diego and Andrea Della Valle have confirmed him for next season and I have repeated it myself.
"Prandelli has also said many times that he will stay in Florence, even if in one Press Conference he made it understood that he has some doubts about the project and the new stadium. The owner instead has never had any doubts."
