I don't like it at all as a coach
Presumptuous, not so good.
He manages to do well when he already has a team with talents and that works, anyone like that (even me) would be able to do well
With Roma he did well because the team was already doing well, if you look at the last few seasons. He had a bit of luck (that one)
Mourinho is a typical arrogant coach, which many people know. I think he is one of the best coaches out there at the moment but surely we will rarely see him coach any mid-table team, Real Madrid, Chelsea, Tottenham, Manchester United, Inter and Roma is a list of teams he has coached. Of course he coached a talented team more often than others, so he was quite lucky about that.
I don't think he can be as successful at Inter, Chelsea or Real Madrid. At Roma, he will not be able to achieve that success easily even though Roma are a good team in Serie A.
