He is a poor manager with no tactical sense and doesn't learn from his mistakes
He is good at motivating and that's about it.
That was before his luck ran out.
He took over when we were hurtling towards the Conference on the back of 10 straight defeats, but comfortably kept us up and then managed to get a limited squad into a playoff position the following season.
If you ignore those notable achievements then yeah, he's a poor manager.
Well let's see he can do with a much better squad. I hope he proves me wrong, but somehow I doubt it.
