The Italian international had been linked with moves to Manchester City and Marseille in recent weeks.
“I’m very happy here and I have a three-year contract with Fiorentina,” the 28-year-old frontman told Corriere dello Sport.
“The rumours are just words. If a club really wants a player, they will move in silence and take him. This has not happened, not with Juventus, Napoli or Manchester City.
Interest
“(Marseille coach Didier) Deschamps is the only one who has expressed an interest in me, but maybe that is because he knows me well.
“He is set to play in the Champions League and is looking for a new attacker, but I feel great in Florence and I want to win things here.”
