AC Milan hero Billy Costacurta has questioned Arturo Vidal's ability at Inter Milan.

Vidal was hooked at halftime for Sunday's 6-2 victory over Crotone.

Costacurta said, "I believe he's not physically well and that the challenge is dictated by that.

“He thinks he's fine at 33, in reality he doesn't get to the ball in time.

“I couldn't tackle in that way when I was his age, but I realised it."
