Report by Mundo Deportivo but can see their guess being true.
If Max wins the treble or Serie A-CL double, not much else for him to achieve here, and motivation under status quo will be an issue. So I can see him leaving. Club is also always a step ahead and can anticipate the motivation part.
And if we don't win the CL, can see Agnelli appointing Zidane to win it. Not sure if that'd be the right decision or not, but it's only win-win.
