You want the club to give a charitable contract to persuade him to stay? If he wanted a contract for next year, and wanted to fight for a jersey, you would think he would stay. Charity contracts has never got this club very far.He doesnt have a contract for next year ....if the club want him to stay simply offer the bloke a contact for 2021 and indicate you want him around.
Or simply, that he is putting him family above his contract, and contract or no contract next year wouldn't change his mind. Nothing wrong with that.
