The 23-year-old was at Milan for the 16-17 season. He was at Spartak Moscow on loan this past season.
Now he wants a return to Italy. RMC Sport claim that a move to Fiorentina is on the cards, with both parties already negotiating.
It does not appear that Pasalic has any future at the Blues, as he is not among those being considered for a first team squad place next season.
