That's according to former Chelsea man Tony Cascarino, who doesn't believe that Guardiola wants to sign the Borussia Dortmund striker as the "ultimate difference to his team."
The 20-year-old Norwegian forward has been linked with Barcelona alongside different Premier League clubs, including City, United and Chelsea.
Haaland is under contract with Dortmund until 2024, but the German club may try to profit on the City target now ahead of his £68m release clause becoming active in 2022.
Now, Cascarino has suggested the Norway international would be a more "viable" acquisition for United, who are "screaming out for a player like Haaland."
The 58-year-old former Republic of Ireland international told talkSPORT: "I don't believe Erling Haaland fits into the way Man City play.
"I think Pep Guardiola's wide men and midfielders have a certain style and if you look over the course of this season so many players have played in the centre-forward role, from Phil Foden, Kevin De Bruyne, Bernardo Silva has played there, Riyad Mahrez [...].

"So, I don't think he [Guardiola] is looking at getting Erling Haaland's signature as making the ultimate difference to his team.
"Man City play a false nine and they've done it brilliantly. Teams have found it very difficult to stop them.
"Guardiola might say, 'I don't really need that type of centre-forward,' and some people will say that's nonsense.
"Well, from what I'm watching week-in, week-out, City are playing a certain way and it's really effective.
"Chelsea or Man United will look far more viable to me, with the way they play.
"Probably more so at Man United -- they're screaming out for a player like Haaland!
"Plus, the thing we need to remember here is, and I know it's not Haaland it's his agent, but you want players to come and play for you, not tout themselves out for the best deal financially in world football.
"Wherever he's going, he's getting a great deal, but managers want a player to come to the football club because you want to be there."
