The summer transfer window has slammed shut and Manchester United now have to lie in the bed theyve made. United spent over £150 million on new players in the market that has just closed as manager Louis van Gaal desperately attempts to slam the breaks on their worrying slide in form. There will be no further opportunity to strengthen his ailing side until January and when the Premier League resumes after the international break we will see just how successful his summer signings are. Six new players have come in Luke Shaw, Ander Herrera, Marcos Rojo, Angel Di Maria, Daley Blind and Radamel Falcao but some fans still feel the real problem areas of central defence and midfield have gone unaddressed. United's defence does indeed look brittle despite van Gaal having repeated opportunities to bring in reinforcements while question marks still hang over the midfield areas with the likes of Anderson, Marouane Fellaini, Ashley Young and Antonio Valencia all putting in abject performances over the last few months. The Red Devils will have to wait now before contemplating a further rebuild, because January is some four months away, which is an awful long time in football. There is at least an option of using the winter window to splash the cash and make any necessary changes to the team that still need to be made, and with that in mind, here we take a look at 10 Players Van Gaal Must Target In January.
