The rumours surrounding Arturo Vidal continue with Chile manager Jorge Sampaoli claiming Manchester United want Arturo Vidal, but “have doubts on his knee.”

United haven’t hidden their interest in the Juventus midfielder but the supposed £45m price-tag has raised some doubts over a move to Old Trafford.

“Manchester United want Vidal, but Van Gaal has some doubts,” Chile Coach Sampaoli told El Mercurio.

“Vidal set a great example at the World Cup in Brazil by playing when he wasn’t in perfect shape.

“Now Manchester United want him, but what’s holding up the transfer for $80m is that Van Gaal has doubts on his knee.”

Vidal is currently in Indonesia with Juventus on their pre-season tour.
