Fiorentina coach Stefano Pioli is unsure if he can count on Nikola Kalinic for the new season.
The striker has pushed for a move to AC Milan.
"The sooner I have a complete squad at my disposal, the happier I will be. The club knows that," said Pioli.
“There are several situations that need to be clarified and defined. I spoke to all the players, Nikola is as available as the others, but his situation is not yet defined.
“Vitor Hugo will take a little while, because in Brazil he didn't make the same movements he'll need here. I am sure he's got everything it takes to make his mark.
“In a 4-2-3-1 system, Matias Vecino can play in the two midfielders. There will be games where we make different choices."
