Understandably so though really, presided over a home defeat to the Faroe Islands with Greece, managed a lot of big clubs after Chelsea but realistically failed at all of them, other than a little spell at Parma hadn't been involved in a relegation battle (which Leicester were expected to be in) for a very long time, the last one was Atletico Madrid when it was pretty much his fault they went down and that was back in the late 90s. Of course a lot of people have been proven wrong, I don't think anyone dislikes the bloke because he's evidently one of the good guys and always has been, but on the face of it, it wasn't an appointment that made a lot of sense.
If Wolves sacked Kenny Jackett this summer and appointed say, Steve Coppell, no-one would really consider that to be a good appointment, yesterday's man, not done a lot for many years. He might then go on to take us up but that wouldn't mean the concerns at the time of his hiring were wrong.
