I don't think Evra leaving is the greatest thing in the world. Him and Shaw could have had 50/50 games and bed Shaw in under a LB who once was in the top 2 LBs in the world. Evra's legs have gone and because his legs have gone he does things he shouldn't defensively because he knows he can't get back if he gets done on the outside. It happens.
But now United arguably need a GOOD CB (i.e. Hummels) a young CB who is up and coming to take the place of Smalling or Jones should they not progress (i.e. De Vrij) and then a LB to play in case Shaw gets injured. With Buttner and Evra going, United are now short at LB.
Obviously United need another CM as well and that along with a CB should be #1 priority IMO.
