Yes.
The title winning team of 12 months ago is still there. There needs to be some patching up done, mostly at the back and in CM, but there are the elements of a good team within the United squad, not least the likes of DDG, Jones, Smalling (both of whom need to regularly be played in their best positions of RB and CB respectively), Rafael, Welbeck, Kagawa, Rooney, RvP, Januzaj, Mata and others.
I firmly believe that the major problem this season has been tactics, not personnel. A manager needs to either adapt their tactics to suit the strengths of the players he has or they need to bring in the players to make their tactics work. Moyes did not do either, but that does not make the team we have useless.
Successful acquisition of quality talent plus tactics which better suit the philosophy of the club, the players, the fans and the manager will bring instant dividends.
