What I've liked about him so far is that he's not tried to be too clever. It's a classic problem when (a) sticking midfielders back there, or (b) players are playing up a level and feel pressure to play the same way as the player they're replacing.
Get the basics right. Keep play moving. If in doubt, get rid. It works so long as he can defend and win his personal duels, which he seems able. We need a few more of these steady-eddy types in the squad, now Milner's coming to the end of his career. Fergy had loads of the bang-average bastards, O'Shea, Wes Brown, Smalling, Fletcher, Phil Neville, etc. Nothing special, but were happy with a squad role and did a job when called upon.
