I think that his signings have been, for the most part, decent and he wants to play entertaining football. He has come through his first full season and will now have to put what he has learnt in to practice over the summer so that we can kick on next season. There are, of course, things that need to be improved upon and Jackie (like any manager) will have to deal with those to avoid bringing pressure on himself.
Possibly not the most satisfactory answer but I just have a feeling that he will prove to be a good manager for us if we give him the time.
