I don’t really think there is “a guy”. Poch was as close as we got and that was just a bunch of things aligning and a very good and brave manager being one of those elements. Maybe the example of Klopp at Liverpool suggests otherwise but I don’t think there is a messiah out there for us and there are a lot of things wrong at our club.
However, there are some managers who just aren’t up to it. I think it was Carragher who made the point recently that he can’t remember any manager in recent times who was successful at a lower half club playing functional/pragmatic football who was a success when they got a big job. Nuno, Hodgson and Moyes are all good examples of what he’s talking about. That’s why I have major doubts on Frank but I am willing to reserve judgement until he drags us into a relegation fight or until he has a full season.
That said, most of what I’ve seen to date, from the performances to the players’ behaviour to his utterances in press conferences suggest to me that he’s out of his depth.
