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.
I don't think Haaland will have a hard time scoring goals in his first season at Manchester City regardless of how many he manages to score. But obviously many doubt it because the Premier League is still much different from the Bundesliga where the Premier League is still better than any domestic league. Haaland is an smart player and he knows what role he plays in the Manchester City squad, so I wouldn't doubt his quality and his ability to score goals.
I'm sure he will shine at Manchester City, he will get a lot of support from other players and that will help him get better. I think we can see his performances since pre-season, so I don't have to doubt it too much.
Yes, I think Haaland will not be difficult to adapt. Haaland, is known to have played for Manchester City in the Premier League from 2000 to 2003, although at that time he was still very young, he certainly understood the atmosphere of the Premier League very well. The presence of Erling Haaland certainly makes the Man City squad even more frightening. Haaland will quickly shine with Manchester City, because as a pure sticker, he will always be spoiled through measured passes by the Manchester City midfielder who is known to be very creative.
