Went to fiorentina on an 18-month loan, but got a private agreement with them giving him the ability to terminate the deal earlier if he wanted. He had until June 30 to communicate his intentions to Fiorentina, never did, then afterwards(with him pretty much already having an agreement with inter) he told fiorentina he was leaving. Inter pulled out after Fiorentina took the player to court, and he signed with Roma instead. He eventually won the case anyways, but it was very cnutish behaviour on his part
Cheers, I remember hearing something but didn't know the details.
