The Chile international is understood to have emerged as Louis van Gaal’s top target for the coming months on the back of his World Cup showings, with the Dutchman desperate to partner Ander Herrera with a competent box-to-box midfielder.
Vidal has starred for Juve during their recent successes, but despite United’s lack of Champions League football it is said that the player himself is open to a move to Old Trafford.

United were watching Vidal while David Moyes was in charge, but a move for his services failed to materialise.
