I think a lot of people on social media (and TV) are criticizing Haaland for things that are outside of the scope of his current role. Haaland is not without weaknesses (see his first touch last night), but his current role is playing as a pure striker. I can't be mad at him for not having many touches when that's how Pep has instructed him to play.
Is Haaland's role getting predictable? Now that's a reasonable worry. Haaland needs someone to help stretch the defense and open the space for him to run into. Otherwise, he just turns into a decoy. Maybe getting a creative pacy winger could help him. Maybe Pep could change the tactics and get Haaland more involved by teaching him to play a bit more like a proper center forward and less like a poacher? He'll never be Kane or Suarez, but I think he can add more to his game.
First let's see how the season goes. It's still too early.
