I'm not sure how people arrive at their expectations. To win the title every year in in Germany for Bayern Munich or Italy for Juventus might be considered normal, but in the PL 1 in 2 is phenomenal given there will always be strong challengers. Sir Alex won, what was it, 13 in 20+? Of course, Sir Alex was on a different level of greatness considering he both A) Built our dynasty and B) maintained, and didn't have the obscene wealth City do (but we were still bloody rich regardless). However, no matter what your wealth, the PL has other big clubs, and can never be a league you can expect a Bayern or Juventus type domination. For a manager to come in and win 3 in 5 is absolutely fantastic and one should be grateful for that if they're City fans. This is their most successful period. Of course he could have done better in the CL, but let's not forget that even all time great managers win the competition 1-2 times in their entire 20+ career span. So with the cups, winning it is special. Not winning it is the norm. People forget this.
Having said all that, of course City have spent absurd amounts of money and did already have a pretty good team (although with many issues hence the 2nd and then awful 4th placed finish). Which is why I don't put Pep ever a long side Sir Alex as he lacks certain qualifies the great man did. However, as a coach, in terms of tactical imprint, in terms of raising City's level of football (90/95 point seasons, winning runs, multiple league titles, domestic trophies etc), Pep has been a resounding success at City. All I can hope for is that once we've seen the back of him and Klopp, we have a top top manager at OT to take over.
Edit: With a manager like Pep, the first season coaching the players is usually a learning phase. We used to say 5 in 7 for United under SAF not 5 in 10 as we all knew there were years spent developing the likes of Rooney, Ronaldo etc.
