Van Gaal will probably sell half Utd's team. Expect to see a lot of Januzaj, Zaha, Cleverley, Bebe as he slowly turns you into Mancelona.
I will agree that PL football is often extremely archaic and formulaic. For instance you basically don't see any consistent pressing in the opponent's half (or even outside your third) from most teams or have them repeat formulaic "send a winger, cross, try to score" attacks ad nauseam. For fuck's sake, half the league still relies on hoofing the ball forward...kick & rush and all that.
But some teams still play fairly modern, show synchronized tactical / spatial movement and all that.
But all in all their league is currently easily the most entertaining out there, especially since it's legitimately contested and not in the claws of an evil hegemon or two.
