Real Madrid are ahead as well - they've scored lots in the last couple of years. 118 in the league alone last season.
It doesn't alter the fact that his underlying "big picture" numbers are superb. As examples:
i) Goal Difference in the league in his 2 and a bit seasons is now up to 127. That is a huge 72 goal difference higher than the Rags and 49 higher than Chelsea over the same period.
ii) Goals scored in the league in his 88 league games is vastly superior to the "rivals":
City 211
Liverpool 166
Arsenal 161
Chelsea 160
United 143
iii) Defensively in the league we are only 2nd behind Chelsea in terms of goals conceded over the 2 and a bit seasons - 84 compared to 82
iv) An interesting shift is in the number of "goal attempts" conceded per game. In the title win season 13/14 we had the fewest attempts against us @ 9.4 per game. Last year we were third best @ 10.2 per game which is still very good (Mancini was 10.4 in 11/12).
This year we are running @ 7.2 per game which is so low it is as sensational in my eyes as the goals scored figures you highlighted and as far as I can see is pretty much unprecendented in the Premier League and is obviously the lowest of any team in the league this season and the 4th lowest in Europe.
v) You mention Champions League away record. His all-time record in group games away from home might be the best of all managers (I'll check this out at some point). Simply, with the 4 clubs he has managed in the CL he is losing only once every 10 games.Home form could do with improvement :)
Keep up the good work Manuel.
