If City were really that good they would have won the CL by now, especially after dominating the Premier League.
That says two things to me, either the Premier League isnt as strong as they all say it (a 1/2 horse league just about every year now) or that City arent quite as good as we are all lead to believe. I believe the latter.
i dont want to bash Pep as he is quite entitled to picking his jobs, but hes never tested himself the way other managers have done (and been as successful).
Jose got a Porto side the Uefa and Champions League. Conte won titles at Juve Inter and Chelsea. Hansi Flick won the league and CL in the same season with Bayern. Pep has won titles every where he’s been able to spend, would be interesting for him to go to a small/poorer club and see him make a difference there.
Or it says that the CL is really, really hard to win (unless you're Real Madrid) and requires an element of luck no matter how good you are because that is the nature of a knockout competition featuring the best teams in the world. City have made Chelsea (away), Liverpool (away) and PSG (away) look absolutely silly this season and come away with a losing aggregate of 3-4 in those matches, so of course they're beatable in a knockout format. But if you look purely at their performances, personally, yeah, I think they're that good with only Bayern matching them or being better (I'll be honest, I don't watch enough of the Bundesliga to have a strong opinion on this). Maybe they're missing that extra bit of individual magic in front of goal, but they're lethal everywhere else. Also, I don't think there's any denying Pep sometimes overthinks the big games in this competition so he's not blameless. I just think sustained greatness in a strong league is far more indicative of how good a team is than a knockout competition, no matter how prestigious, and this City team have been relentless in that regard in the face of some great competition (Liverpool).
As for the second point, I used to be one of these people too, mostly because I found the Pep/Barcelona fanboys insufferable and wanted them to be brought down a peg, but what exactly would the point of this be? You can say he had all the resources at his disposal, but he aced his first job and won everything there was to win. Why should he take a step back and work with lesser players in the prime of his career? Is there a single manager of his stature and ambition that would do this? Even "the people's champion" and world's most successful underdog Klopp has steadily gone from bigger to bigger clubs. Pep winning in Italy or at Chelsea would prove nothing, it would just be reframed as, "of course Pep wins, so boring and predictable".
If you really want to see what Pep would do with limited resources, might as well watch Brighton. They're an impressive team who will probably never win anything because the players aren't good enough.
