i fear they may dominate the league like Lyon, Celtic, Rangers, Juventus, PSG, Bayer did/have done.
A lot depends on the outcome of the current investigations. If no action is taken then FFP is effectively dead.
Guardiola's huge spending has lead to the big clubs lobbying UEFA to take action. City, knowing eyes are on them have reigned their spending in to a degree. It's taken much deception & creative accountancy but they've still managed to put together a world class squad. It's crazy to think of the players they'd have if they had unfettered access to Mansour's cash. They could easily spend to the point where there is no drop in quality from their first to their second team.
Clubs that have won Championships 4,5,6 x in a row have had massive financial dominance over their leagues. This is a new phenomenom in English football. It's not unfeasible that City could go on a run like Juventus, PSG, Celtic, Bayern.
