According to the Daily Express, United have moved into pole position to sign the Argentine international. And Di Maria is willing to join the Old Trafford club, if they match the £120,000-a-week wage package PSG were prepared to offer him.
The Parisian club had agreed personal terms with Di Maria, but were forced to end their pursuit due to Financial Fair Play regulations. Having signing David Luiz for €50m, they must sell before they can buy again.
Real Madrid's stars are keen for the Bernabeu club to keep Di Maria at the club, and Cristiano Ronaldo and Sergio Ramos have reportedly lobbied Florentino Perez.
But the Real Madrid chiefs want to sell the Argentina international to recoup some of the money spent on their big summer additions, Toni Kroos and James Rodriguez.
Colombian international Rodriguez in particular is expected to take Di Maria's place in the Real Madrid midfield. Di Maria played as one of the three central midfielders in Carlo Ancelotti's system, operating as the shuttler between midfield and attack.
Louis Van Gaal reportedly has his eye on the £50m-rated midfielder with a view to playing him out wide. That would allow Van Gaal to revert to his preferred 4-3-3 system.
At the moment he is using a 3-5-2 formation with wing-backs to compensate for a lack of quality in wide areas. Winger Nani was recently allowed to return to Portugal on loan as part of the deal to bring defender Marcos Rojo to Old Trafford.
