Man United line up three defenders after missing out on Arsenal star, including Chelsea target

1) Mats Hummels (Borussia Dortmund)

Above all, Manchester United’s top target in defence is Borussia Dortmund star Mats Hummels, who has long been linked with a move to Old Trafford. Arsenal recently showed an interest in the German World Cup winner as well, but it now looks likely that van Gaal will step up his efforts to bring in the 25-year-old this summer, as he may be available for as little as £20m – certainly a bargain for a defender of his quality.
