I think City being a great team plays a good role on this as well, Haaland is amazing but you can't put Haaland at a team like Everton and expect him to get the most goals in a season, that would not work, they do not get enough scoring possibilities.
Of course you are correct Haaland is a very good player, he is one of the first Bundesliga player to come English league and perform the way he does, he is actually one of the best striker on premier league that scores almost all there matches.
However like you said Haaland can never be at a club like Everton because his chances of scoring the way he does on Manchester City will no longer be there because his performance was dependent to the kind of tactics Manchester City has so going to Everton may be very difficult for him to cope.
I don't understand, do you mean Haaland will play at Everton by leaving Manchester City or something else? LOL, I think there are no factors that will be able to make Haaland leave and join Everton . Because after all, the fact is that Manchester City have also not yet played against Everton so far this season and also, Manchester City schedule against Everton it seems is still long . So yes, I still don't understand what you mean about Haaland and Everton, because I think there is no basis and or related issues about them either so far.
