Trapattoni said: âWhen the right train goes by, you have to get on it. It can happen once, twice, three times. Not a thousand.
âSuddenly you can find yourself old and forgotten. Mario is riding an uncontrollable powerboat, he mustnât waste this moment of his life.
âAbove all, his agent Mino Raiola must not see him only as a goldmine to be taken advantage of, but help him understand his mistakes.
âMilan have some talented players. I bet this season weâll see the explosion of Stephan El Shaarawy on the scene.â
