Manchester United are prepared to commit as much as £100million to their pursuit of Angel Di Maria as the ailing Barclays Premier League club try to beef up Louis van Gaal’s squad before the end of the summer transfer window.

United manager Van Gaal is desperate for world-class additions and has told executive vice-chairman Ed Woodward to do all he can to bring winger Di Maria to the club from Real Madrid.

It is understood United have told the Argentine that, with performance-based incentives, they will pay him around £200,000 a week. Over a five-year deal that would take the club's investment to £100m when a transfer fee of around £50m is included.

A salary that size would put the 26-year-old in the same ballpark as Wayne Rooney and Robin van Persie.
