Personally I would only rate him 6/10, as he has not lived up to my expectations. I think I expected more, given his footballing pedigree. I have a number of concerns.
First of all, his inconsistency. He seems to contradict himself such a lot. In the past he has made it clear that he strongly favours a 3-5-2 formation, yet he often starts 4-4-2, or switches part way through the match. Then after a recent winning streak, he tries 3-4-3 and we lose. I can't help feeling that he is still experimenting with his team, and sometimes they don't know which formation they are supposed to be playing. Despite making a case for these systems, he has contracted himself more than once in press conferences by saying "it's not about systems".
I worry about his motivational skills. He frequently complains that the team has underperformed, but surely it is his job to motivate them. I'm still at a loss to understand what went wrong last season, when we didn't win for 17 consecutive matches, and only drew 4 of them. That was a disaster, especially when we had been doing so well in the previous matches since he joined us. In any other club, his job would have been on the line.
I get the impression that there could be personality problems, which would account for why we lost key players at the beginning of this year. I also don't think it helps to chastise his players so publicly (eg. “I took Harry Middleton off because he was poor.") He needs to earn the respect of his players, so that they want to do their best.
I don't understand why we get so many injuries, including those which are sustained 'in training'. To have 5 long term injured all at the same time seems to be more than a coincidence - especially when 4 of them are defenders. Is it just bad luck, or are they not as fit as they ought to be.
Last season he had the excuse that most of the players had been engaged by Dickov. Now he has got rid of all those he doesn't want (N'Guessan being the last) and has engaged those of his own choice.
I agree with you that we are nowhere near settled in performance yet to guarantee an automatic promotion. Last season at Christmas we were comfortably placed around 15th or 16th, and look what happened then. My concern that something similar could happen again. I hope not!
