Fiorentina have agreed terms with Partizan Belgrade over the transfer of Adem Ljajic to the Serie A club.
The 18-year-old attacking midfielder will become a Viola player pending a medical examination.
A statement from the club said: "Fiorentina announces that an agreement has been reached with Partizan Belgrade for the signature on a permanent basis of player Adem Ljajic."
Ljajic came close to joining Manchester United but the club announced at the start of December they would not be taking up their option to sign the player.
The Serbian Under-21 international is considered one of his country's biggest talents and his abilities have led to him being nicknamed 'Little Kaka'.
