About sums it up. I listened to the interview and he comes across as a thoroughly nice bloke who automatically fell into football because of his Dad. He then worked hard and became the player and icon (for Chelsea) that he was. Unfortunately, it's quite clear how much he loves that club and that makes being the coach of another team much harder.
He was lucky to fall into the Derby job, luckier still to get the Chelsea job, fortunate to then get our job and then incredibly to get fired from that and go back to Chelsea. All the time, achieving precisely nothing.
He doesn't have the hard nosed attitude you need to be a top coach. Just that simple. Would be a Peter Taylor to a Brian Clough, at best.
