Manchester United 'to bid £1.5m for Aston Villa defender Ron Vlaar'

Manchester United are reportedly prepared to test Aston Villa's resolve with a bid for defender Ron Vlaar.

The 29-year-old will become a free agent in the summer, but reports have claimed that United want the Dutchman before the end of the January transfer window.

According to the Daily Star, the Red Devils will offer £1.5m to Villa for Vlaar, who has also been linked to Liverpool and Arsenal.

Villa are believed to be willing to let the defender leave for nothing in the summer in order to keep him for the remainder of the season.
