I'm not absolving Moyes from any blame here, Barney. My gripe here is (if you've been following the thread) that the current players are so set in their ways and used to one, singular system, they're virtually impossible to alter. Most of our squad - the likes of Ferdinand, Vidic, Smalling, Carrick, Cleverley, Fellaini, Valencia, Young, Hernandez etc. - simply aren't flexible enough to adopt a differing system. The three defenders I've mentioned simply lump the ball forward at every opportunity, Cleverley, to be fair to him, prefers the 'pass and move' approach but he's too slight to be an imposing central midfielder in England, Fellaini has his strengths but they lie away from a 'pass and move' system, and the attackers I've mentioned are far, far too one-dimensional.
I really believe another manager would've struggled to successfully alter the way we play. A Mourinho might have instilled more confidence in them, but as for changing their whole games around, I doubt it.
