Man Utd Transfers: 10 Players Van Gaal Must Target In January

6. Mats Hummels

But he could try. A dream January signing for Manchester United in January would be the aforementioned Hummels, who was linked with a switch to United for much of the summer before staying put at Borussia Dortmund. Though Louis van Gaal didn't make an offer for the centre-back, recent reports suggest he was looking at him in the final week of the window. With United's defence looking as brittle as it is, Hummels would instantly improve it. A commanding centre-half, he is the authority figure the Reds currently lack following the departures of Rio Ferdinand and Nemnaja Vidic. Strong on the ball and good in the air, the 6 ft defender would certainly add steel to United's rearguard. His club are unwilling to sell, however, with Dortmund manager Jurgen Klopp laughing off speculation linking him with a move to Old Trafford recently. Quite whether that stance softens in a few month's time remains to be see, but it cannot be denied that Hummels would be a fantastic signing.
