Both clubs announced the news several hours after the medicals and Rebic’s contract had been deposited with the Lega Serie A.
It had been thought of as a one-year loan with option to buy at the end of the season for €25m.
However, the statements show these are both two-season loan deals with no options to buy.
There were some concerns over Andre Silva’s medical, which had already scuppered his move to Monaco last month, but it was considered not serious enough to terminate talks.
