To do that they will need to strengthen their defence after Rio Ferdinand, Nemanja Vidic and Patrice Evra all left the club.
And according to the Daily Mail, van Gaal is doing exactly that as they report that German international defender Mats Hummels looks set to sign for the Red Devils.
Reports suggest that a £16 million bid has put in place and the two clubs are now locked in talks with the Old Trafford hierarchy who are confident that a deal can be done.
The 25-year-old was very impressive during the World Cup and that form has seen van Gaal target him as the man to build his defence around.
Former Southampton defender Luke Shaw will of course join him in that defence following his £30 million move from St. Mary’s but there is likely to be more signings coming in.
Manchester United fans. The signing of Hummels would be a superb addition to your defence alongside Shaw. But who else would make your first eleven defence? Let us know your thoughts below.
