United turn their attentions to £20m-rated defender.
Manchester United could make a £20m bid to Borussia Dortmund for defender Mats Hummels as an alternative to former Arsenal man Thomas Vermaelen, according to the Daily Star.
The German international, a World Cup winner with his country in Brazil this summer, is widely regarded as one of the top central defenders in Europe at the moment, and would make a top class addition at the back if United could get him.
Arsenal themselves have also been linked with the 25-year-old, but United now look to be stepping up their efforts to bring him to Old Trafford this summer, with Louis van Gaal still in the hunt for a new signing at the back after missing out to Barcelona for the signing of Vermaelen.
United still have gaps to fill in defence after seeing both Nemanja Vidic and Rio Ferdinand leave the club this summer.
