Also, in terms of Vlahovic, you're overlooking something: Fiorentina hate Juventus and have for decades, and on top of that their fans' track record when Fiorentina sell players to Juve isn't particularly pleasant, with them literally rioting when they sold Roberto Baggio to Juve to the point bricks and molotov cocktails were thrown at the club's offices, while the only reason the club escaped similar wrath when Federico Bernardeschi made the same move was because Bernardeschi did a Judas
So with that in mind, that does give Fiorentina options: do they risk their stadium being burned down by selling Vlahovic to Juve, or do they have valid reason to consider another option that is available to them?
