This is looking really good so far. I really liek the off the ball movement by the players. United finally look like they are playing modern football and I have to say this is very fun and pleasing to watch. The end product will surely come.
One thing that bothers me though:
United's midfielders play a bit too far up the pitch. They play like they are standby strikers, but that means that you lack passing options about 10-15 yards behind the box.
This is especially true in the half rooms (you probably dont call it that, its a literal translation of the German term: it it basically means the part of the pitch that is neither the center nor the wings). If you had a player going back a bit and going into these half rooms depending on where the ball currently is, you would kill QPR.
