The midfielder has been linked with Inter Milan.
"I have read of Inter's interest and that is pleasing, but there is nothing concrete about the rumours," he stated.
"I am a Fiorentina player and I can categorically rule out a January departure. I'm 100 per cent sure of that."
Although the former Atalanta player insists he'll see out the season in Florence, he won't dismiss a summer switch.
"I need to think about the future and it has nothing to do with money," he continued when asked about his hesitancy is signing a Florence extension.
"I'll soon speak with the club again, without any problems, and the situation could be a lot clearer in two or three months."
