Manchester City is showing how a team should be run. They are not going out there and spending 100+ million on a player and get a star. They are getting players who Pep religiously watched and scouted and knows would work perfectly for his style. They paid 40 million and under for all their players so far, and I am sure they will keep that up.
If this goes on, they are going to build such a high quality and sustainable team that even after Pep they could do very well. I am not sure if they could make this work easily because they lost this season and if they keep losing then the money will run dry and they won't be getting same quality players, but they could keep trying their hardest to at least keep this momentum going.
