sake and to say, Manchester City is very complete in their squad, even if Sterling and Jesus leaves the club there is still right wing Mahrez, central Haaland and left wing Fodan to take the lead. Other good players including Grealish is still in the team. KDB is always there for reinforcement.
The issue I'm seeing in the squad is the alleged departure of Fernadinho, if the movement is to happen, Manchester City will need a good defensive midfielder to scale the season.
Without Gabriel Jesus Manchester City have been completed team on Primer League right now because they have potential player not only as regular but also with substitutes player. I think on forward line Pep Guardiola have many option with right and left winger side, beside still have Foden, Mahrez, Sterling and Jack Grealish have make Manchester City do not really care how busy match every weeks. But waiting with new Manchester Player Erling Haaland how his performance first season with Manchester City, keep ever scoring goals like on Dortmund or Haaland will faced difficulty for scoring goal on Primer League.
