Tbh, Haaland would've been a potentially bad deal for us. Some great factors, but some questionable ones too. We pay through the moon for a Madridista, one with a slimy agent, potential injury problems, so far not really proven at the really elite level, while also playing for the team whose players tend to flop under pressure? There's a chance for a Dembele-like outcome for sure.
Madrid already schooled everyone by securing the best player in the world for no transfer fee. Every other so-called galactico signing just pales in comparison with the real deal.
Just try to go the Liverpool route, by having an extremely disciplined, hard-working, and cohesive team. And, in time, try to develop our own players to a world class level, as Bayern and Liverpool did with the likes of Gnabry, Coman, Mane, Salah, etc. Do that and we can compete.
