I don't care if Haaland's dad played for us or not, he doesn't suit our playstyle at the moment. He's very similar lukaku, who's also a brilliant player but not suited to our football. His passing and technique is far below the standard required to play as a striker for us. Fantastic player on his day, and could still do a good job at City, but we will not get the most out of him in unless Pep drastically changes his system.
People who actually watches Haaland instead of just highlights and stats will recognize that he needs space to run in to in order to be effective, which is space he will not find against the low blocks the opponents always use against us. He's not suited to us the way Werner isn't suited to us either, both brilliant players but would suit a more counter based team like United or Chelsea better, hence why we passed on buying Werner.
More all round strikers like Lautaro Martinez, Alexander Isak or even Sebastien Haller would work a lot better. They are players who can create chances on their own or link up with teammates really good. While Haaland is a top notch finisher he might as well be a 70m training cone when we struggle. For people who bring up Mbappe he doesn't work as a lone striker, not even in the french league. He needs a striking partner or to play on the wings to be at his best
