If he doesn't score or get chances he looks completely useless. That's not his fault either and isn't even a criticism. We knew what kind of player he was and it is up to us to make it work. He is one of the best goalscorers and difference makers in world but he is never going to be good at all around game.
Having 9 outfield players who participate in the build up of the attack is worse than 10 like we had last year, especially against bus defenses. That's just how it is and not the fault of Haaland. We don't create as many chances with him in the team over the course of the season as we did last season, but we sure as hell can score more goals out of the lesser chances we create.
I think Guardiola hasn't yet found a good balance. He wants to have the same control we had last year but to achieve that with one less player taking part in the general play results us in being more pedestrian. To get the most out of Haaland you have to take risks and acknowledge you are going to concede chances and goals due to possession losses, but we'd create more chances too.
