Broader point but regarding the idea that we'd still be miles behind City, well yes. Aside from cheating, they got to where they are by building across many, many years to suit the style of play of a brilliant manager who they were planning for even before he arrived. It would equally be many, many years before we have the level of depth and quality to actually be on par with them, even if we do everything right.
But you can still be very successful well before hitting that point. During the "peak" of Klopp's Liverpool they still had nowhere near the depth of quality City did, a far more workman like selection of midfielders (Wijnaldum, Henderson, Can, Milner, Fabinho, Keita, etc.) and were obviously far less dominant across multiple seasons.
But that was still enough for them to win the PL, win the CL and to narrowly miss out on winning both a second time, because they were still built to be a high functioning team. I'd happily sign up to that sort of inferiority to City over the next four years.
Point being we should be less concerned with how players we sign match up to City man to man and more concerned with how well they help us become that sort of high-functioning team in our own right.
