At first I thought you were kidding but k. The imagination of a football fan is a wondrous thing. allow me to add some unique selling points too. Maybe He can play up driving Chevrolet cars?
having studies this clip; Jose has spent nearly 5 years in London so he knows the London slang pretty well. Jose can polish up Paul's proper "ghetto London" slang so to speak, selling the idea of Pogba the grime MC for when he is done with football.
Or maybe, when the players are jogging onto the field to the O.T. announcer, "Ander Herrera, Wayne Rooney, David De Gea"etc Jose can sell the idea that when Pogba runs onto the pitch, he can have Stormzy (also of Adidas and owner of his own Man utd shirt) rapping along to his intro saying "Man try say he's better than Paul Pogz, tell my man shut up!" that could work.
Or worst case scenario they can hang out after training writing grime lyrics while Rui Faria is on the beat. could work also.
it's these little things that make player want to join a club, not so much the promise of money and silverware.
