Pep Guardiola discussed Erling Haaland's situation in an interview and touched upon the topic of competing for the title.

Will Haaland be rotated?
Pep Guardiola stated: "He feels in excellent form at present and has no physical issues. There may be matches where he appears fatigued, and he won't feature then. Our current situation is that the Champions League is of paramount importance. As for the Premier League, I don't believe Arsenal will drop many points – that's the reality."
This season, Haaland has started 15 matches across all competitions for Manchester City, netting 19 goals and providing one assist – averaging 1.333 goal contributions per game.
