It is absolutely difficult to put a figure to the number of goals Haaland will score this season but it is nice to see that he started the season very well, scoring an average of two goals per match. That is a record that not too many players have and if he continue at that pace, then your estimate will come to pass provided he does not get injured, which seldom happen. One thing I know is that he will win the highest goal scorer in the EPL this season irrespective of weather Manchester City wins the league or not.
Haaland is a player who has a big influence on his team because his performance has contributed greatly to making him a player who is currently ranked highest in goals scored. I can't imagine what it would be like if he had a serious injury so he had to be absent for some time, would it affect his team or not, but what is certain is that if Haaland had an injury, Pep would definitely find a way to overcome it even though it would be difficult for him, after all, it is rare for something like this to happen.I agree with you, whether Manchester City wins or not, the big chance is that Haaland will probably be the player who scores the most goals, as long as he doesn't get injured, I think this will really happen.

If you remember, there seemed to be a moment when Haaland was injured if I'm not mistaken a few seasons ago I don't remember for sure, but Manchester City still managed to make a lot of goals in each match at that time, and Foden also had a big contribution at that time when Haaland was injured. So in essence, Manchester City are basically a great team under Pep Guardiola and despite injuries to key players, but Manchester City have always managed to dominate the Premier League.
Also, in the last two seasons Haaland was in fact the top scorer in the Premier League, so it's no surprise that at the start of this season Haaland is still managing to consistently score a lot of goals too. Of course, the success of Manchester City is due to having the best manager, because with good finances and Pep Guardiola managing this team to impress with consecutive trophies.
