AC Milan cannot only focus on signings this summer as they must also make some sales to free up funds and places in the squad.
As reported by Sky (via PianetaMilan), the Rossoneri management do not consider Divock Origi and Ante Rebic part of the project moving forward and at the moment it seems likely they will both leave in the summer.
As for Brahim Diaz, Milan want to sign him permanently from Real Madrid but they would not be willing to spend more than €20m in order to sign him after three years on loan in Serie A.
On Charles De Ketelaere, Paolo Maldini believes in the Belgian more than anyone and wants to give him another chance, also because the contract that binds him to the club is for five years. In any case, if he were to leave it would only be on a permanent basis and not on loan.
