Heh, "messiah" have the team for CL half-finals, and he is out of CL after first round, from weak Bayern and number 7 from Serie A. Honestly, I don't like his performance in CL. Nobody expect this year CL championship, and City CL group was difficult, but ... City is much better than Bayern and Napoli, so they need to won that group. Everything under that is not success.
This is my opinion how things look to me at this moment, and where he need to work to be better.
So from 1-10, I will give him 6, mostly because City is first in EPL and because they are already out of the CL.
Positive
Rags (Old Traford), Bayern (Etihad), first in EPL, Tevez case in general
Negative
Bayern (Munich), Napoli (Napoli and Etihad), Chelsea, out of CL, third and not first place in group A of CL, not even close to CL half-finals where City really belong, talking too much to press, like for example "Tevez will not play anymore in my team" (that sentence cost the club huge amount of the money) even I agree with him that he need to bench him forever, weak defense, too nervous on the games, yoga will help, discussions with players during games, and it seem not in his office before and after games.
