What has Man City achieved that PSG haven't?
They've built and identity with long term thinking. Having a, compared to PSG, balanced team and a much better foundation to win the CL multiple times in the coming years.
PSG are a bunch of mercenaries with only one goal: to win the CL now. Half of their best starting eleven is filled with mediocre players that no one else wants.
In terms of long term stability, Man City are miles ahead of PSG. They might have an equal amount of CL trophies, but City is at least making a name for themselves by winning trophies that are relevant and playing good football.
