The Argentina midfielder has come close to leave Florence in previous transfer windows.
And agent Alessandro Moggi says: "He renewed his contract with Fiorentina last year, at the end of the last transfer window. Fiorentina rejected a very important offer from the Premier League, of €42m.
"The previous summer there had been an offer from another English club. The player is now playing in the Copa America, he is a very important player and is probably the symbol of Fiorentina.
"When there is a contract in place I often defer to the words of the directors: in this case I read those of (sporting director Daniele) Pradè a few days ago, he said that Nico will remain at Fiorentina 99 percent."
