Well, he got Birmingham higher than Villa for the 1st time since the 70's, as they finished 13th and 10th and 12th before being relegated, got Wigan to 11th, Sunderland to 13th and even when sacked they were 16th, all positions higher than subsequent managers managed so I would say he definitely is a PL manager.
I'm not convinced by the comments Steve Harper made about the lack of focus on attacking during training, and that is borne out by the way we seem to retreat into our shells and see what the opposition have to offer, but overall, we could have far worse managers leading us in the Premier League
