'serial bottler' - Everton produced better results consistently under him than most (any?) teams with a similar budget.
In the time he was Everton manager - 9 different clubs won the three domestic trophies, that's it,. And I'd say only 2, at most, were running on budgets anywhere near Everton's budget. Everton are a massive club in stature but, in that decade, we were utterly, utterly skint, I don't get why this has been forgotten.
He might have had his best decade at Everton, and he's now a bit past his best, but no doubt Everton are in a better state because he was the manager.
