The Serbian has made up his mind to leave Fiorentina and has agreed in principle to join the Rossoneri at the end of the season when his contract expires

By Greg Stobart Fiorentina star Adem Ljajic has decided to quit the club and has lined up a free transfer to AC Milan next summer.The attacking midfielder has been given until Tuesday to decide whether to sign a new contract with the Italian club, with his current deal expiring next summer.It is understood the Serbian has already made up his mind to leave Fiorentina and has agreed in principle to move to Milan at the end of the season.Fiorentina would like to sell the Serbian before the transfer window closes next week so they do not lose Ljajic for nothing - but the player is determined to move to the San Siro.Milan have already had an €8 million bid for the former Partizan man rejected this summer and they are now prepared to wait a year to sign him.Atletico Madrid and Liverpool have been strongly linked with the 21-year-old, while he has been mooted as a potential target for Roma to replacement Tottenham-bound Erik Lamela.Fiorentina coach Vincenzo Montella admitted over the weekend that he is “fed up” with speculation surrounding Ljajic’s future."I am fed up of the situation," Montella said. "I think he showed something in the second half of last season, proving that he appreciated the support shown to him by his team-mates, club and coach."I have neither the time nor the desire to wait for him, seeing as he’s not calm and not focused on his work."The team's training session on Saturday was reportedly interrupted by a group of supporters, who heckled Ljajic about his desire to leave the club.Montella added: "The fans can do what they want to, just like Adem. I don’t think a few jeers can condition a player or a club. At times, jeers are a sign of interest ..."Ljajic has scored 16 times in 88 appearances during three years in Florence following his €8m transfer from Partizan.
