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 it eventually happens, it's not the first time Haaland is getting injured. It happened last season or previous two seasons. I can't really recall the exact season but it happened and he was still able to maintain the lead even after being out for several weeks. I won't be surprised if the same thing happen this season. As we can see from the stats, Haaland is already leading with a gap of two goals and Palmer who's second on the table doesn't have equal support like Haaland to score goals as much as possible. Palmer scored four in their last match by the way but we still have a long way to go since we are just six games away out of the thirty eight.
