He's won things at clubs, yes. When he hasn't been sacked or otherwise left within a year of appointment, which he's done a frankly astonishing number of times.
He's a manager on the wane.
To say nothing of the fact that (and the majority of Evertonians) have absolutely no desire to bring in a manager who would spend the whole time wishing he was in charge of the shower across the park.
