By the time the transfer window closes on September 1, Manchester City will hope to have one of the strongest squads they have ever fielded for a Premier League title challenge.
Erling Haaland looks guaranteed to score goals, while Julian Alvarez could be a shrewd back-up if he can adapt to European football in relatively quick time. There is talk of a defensive midfielder and a left-back arriving, and City have promised more incomings to strengthen other areas of the squad.
If four players arrive, though, that means some must leave to either recoup funds or keep the squad size at a competitive number. Too many players, especially in attacking positions, and there will start to be a handful of world-class forwards restricted to occasional substitute appearances. Even if City don't want to lose the likes of Gabriel Jesus or Raheem Sterling, it might have to be a necessity.
