Louis van Gaal's hopes of signing Borussia Dortmund centre-back Mats Hummels appear to be slim as the German international is reportedly content with life at Westfalenstadion.
The 25-year-old is reportedly Van Gaal's number one choice to replace Nemanja Vidic at the heart of Manchester United's defence following his departure to Inter Milan.
However Hummels, who worked under Van Gaal during his time at Bayern Munich, is yet to make contact with the Dutchman.
Hummels' agent Herman, who also happens to be his father, told talkSPORT: "I know Louis van Gaal from his time at Bayern Munich.
"He’s not contacted me about Mats moving to Manchester [United] though.
“I have heard some rumours but Mats is happy at Dortmund at the moment, and only thinking about the World Cup."
Van Gaal may have to switch his attention to fellow Manchester United targets Ezequiel Garay or Mehdi Benatia if Hummels is to stay at Borussia Dortmund.
The 62-year-old has reportedly handed Manchester United chief executive Ed Woodward a list of targets he would like to have at Old Trafford next season - with Hummels among the players wanted by Van Gaal.
Manchester United's recently appointed boss has also been linked with making moves for Marco Reus, Toni Kroos, Luke Shaw and Kevin Strootman.
