He literally took Chelsea to 2nd in the prem, and finalist of UCL, only lose by penalties. I don’t really know how he got the job in the first place as he really hasn’t got a world-class CV before that, but this specific Chelsea season of him just isn’t bad in any way. I know their team is full of world-class footballer but it still takes a good manager to take them that far.
So, what happened?
There was a bit of snobbery going around because he wasn’t a well known name. When Chelsea sacked there was a bit of a feeling he was harshly treated, but his spells at Pompey and West Ham seemed to see that go away (although, I don’t think even Sir Alex Ferguson could have saved Pompey that year)
