The Red Devils are confident of making progress in their pursuit of the Juventus star this week, with Louis van Gaal having given the green light to a move for the Chilean.
The Old Trafford club is increasingly confident of landing the Chilean World Cup star and is looking to make progress in a move for the 27-year-old in the coming days.
Louis van Gaal, who officially took charge at United on Wednesday, is a big fan of Vidal, having tried to sign him while in charge of Bayern Munich in 2011, and has approved a move for the midfielder.

"In Italy, there's the feeling that Vidal may be the marquee player to leave Juventus during this transfer window.
"After the shock of Antonio Conte's departure, Juventus has pushed ahead with a move for Argentinean Roberto Pereyra from Udinese, who could be seen as a reasonable replacement for Vidal in a starting XI that new coach Massimiliano Allegri will switch from a 3-5-2 to a 4-3-1-2."
United has monitored the situation regarding Vidal closely during a turbulent summer at Juventus, which has seen Antonio Conte leave the Serie A champion amid talk of unhappiness regarding the club's transfer policy.
Juventus has signed forward Alvaro Morata from Real Madrid and is set to complete a move for Roberto Pereyra, while suggestions that Vidal could be sold grow louder in Italy.
Vidal, who is currently resting in Chile following the World Cup, recently conceded that his future in Turin looks uncertain.
"I don't feel like my time at Juventus is over, although I can't say more right now," he told a Chilean radio station. "When I'm back from Chile, I'll talk to my executives and we'll see what will happen."
Juve director Pavel Nedved, meanwhile, says that the club is reluctant to sell both Vidal and Paul Pogba but acknowledges that a big-money bid could force it to part ways with the Chilean.
"Our strategy is clear; we want to keep all our best players, including Vidal and Pogba," he told Tuttosport. "We don't want to sell anyone, especially Vidal.
"Certainly, if there were a high bid for them, we'd have to think about it but we don't want to sell our champions. We want to be competitive in the Champions League and the only sales to be players who are not part of our plans."
Publicly, United has aimed to manage expectations regarding signings but Vidal has emerged as its No. 1 target, and chief executive Ed Wooward has confirmed that the club is still in the market for players this summer.
"We've been working with Louis over several weeks with regards to targets and we're continuing to move forward on some of those targets," Woodward told MUTV. "We are willing to invest. There is no fixed budget. Financially we are extremely strong and funds are available. Louis is assessing what's going on and there is a lot of work going on behind the scenes, so watch this space."
