As a player from what is my favourite era as a fan, I'll always like him, but looking at it objectively he'd done nothing as a manager to deserve getting the job and so far, has done nothing to suggest he's good enough for it, or will have any real success.
For me, he seems not to know what to do when plan A isn't working, other than to persist in the hope that it eventually does. Top managers see what's going on and make changes to address the problem, even if it's risky and doesn't always work. He just dithers, the Young Boys game being a good example of this.
He's been dug out of a hole time and again by individuals - usually Bruno Fernandes, and that's papered over the cracks. He's exposed now, because he's been given three world class players and he'll have to deliver. You cannot buy three players like that and not look a better side, but at the moment that's the case.
I would love it to work, but if I'm honest, I don't think it will. I think the club is treading water under him because sadly, I don't think he's not good enough tactically to get the best out of the players he has.
Its worrying that average PL sides seem to know how to play against us, whilst we don't seem to be able to break them down.
