I thought we had to move on as he'd walked away ?
He did a decent job in stabilising a club under the changeover, but never lived up to his billing from most and eventually many, not all, saw that.
Spent more than any other manager and didn't spend it as well as many have or could have done, but still built a squad eventually that had prospects, which he in turn did not turn into the progress his spend required.
On his exit many of his 'advantages' have been shown to be myths, the exit of some players and not others has left the club with some problems, which may restrict or constrain the owners future decisions on manager selection, player funding and who knows what else.
A decent 4 seasons, but his old methods proved more of a limitation than an aid to our eventual success, but overall they were seasons of limited progress and that's good.
How his total control approach, his lack of modern day thinking will eventually affect us short term will depend on RL's next appointment, his departure, the manner of it, especially, tips the balance against him.
Sadly I don't think medium term his influence on the club has yet ended, perhaps in time like other past managers who quit, he may be seen differently, I doubt it.
In summary did well enough but under the circumstances he worked under should have done better, much better if he was as good as many including the media extol, he didn't though.
