Isn't that because you don't really know where the goal is coming from ? harder to defend when the goals are spread around the team and quick intricate passes open up a team depending on who's in the best position not on who's the biggest name or focal point.
I feel the reason why City have looked worse than last season is because now if you stop Haaland you stop City. Last season who do you stop ? Stop KDB, Foden kills you, stop Foden, Mahrez kills you. etc......
He'll still break the goal record and will still probably win the league, do I think they're a better team than last season ? No, do I think Haaland will win them the UCL ? Hell No.
