Oh, you did plenty of "I told you so", and I'm more than convinced he didn't take us to the GF, Walters did!
As much as he is a master at managing a team. He can make a group of players really believe and play for each other, which is absolutely an immense credit to him, as it is very hard to do.
That said, he is way past as a tactical coach. Without individual ad-hoc brilliance from our very talented players, we flounder every time against the top teams.
P.S. Following your own train of thought, why are you bagging Milford who also took us to that GF, and was by far our best player in it?
