The only scenario he'd end up at United is if he's braindead and drools on himself constantly while staring at the wall with a blank stare on his face. There is literally no other reason at all why he would choose to go to a team that hasn't won a trophy in 5 years and is in chaos and has a shit tone of attacking players in the squad already. Ronaldo was convinced by Ferguson and his former teammates thats why Rio Ferdinand knew about it before the news broke out.
Chelsea already bought Lukaku , would be difficult to fit both in the team and to spend crazy amounts of money on bringing him in when they are trying to buy a defender thats going to be costly too and maybe a CM as Saul has been shit since he came.
Liverpool does spend sometimes but not the type of money they need to land Haaland, they struggled to extend Salah's deal , I don't see them pay all the money needed to land him and making him their best paid player, last summer they couldnt spend any money at all.
I'm not saying that they won't talk to the player and his agent about a transfer possibility , but even Barca talked to them and Barca is broke as shit right now. The possibility of another PL team landing him is very slim IMO, maybe sometimes in thr future , but not next summer.
