There has been talk of Haaland's agent Rafaela Pimenta talking with Real Madrid and Barcelona about a move from City in 2025.
But speaking to Tribalfootball.com partners Flashscore.com, Pimenta insisted: "I don't know, but I think the Erling Haaland project is one that will last over time, over the next few years. It will also depend on trends in football.
"In any case, one thing is certain today: Erling Haaland feels at home at Manchester City! He is 1000% committed to the City project and is already looking forward to the new season with the club."
Asked about her claim of Haaland becoming football's first "€1bn" player, Pimenta also clarified: "When I said that this amount corresponded to 'his value', I wasn't talking about his 'transfer value'. I was referring to the value of a top player at that age, with enormous room for improvement - and when I said that, he hadn't even done the treble - a player who finished as top scorer in the Premier League despite being injured for two months... He's a player with great potential.
"What do I see when I make this estimate? I see all the financial considerations that revolve around him, even though he's a serious player who works hard, is organised, focused and never gets lost. He's been at Manchester City for two years now and there's never been any gossip about him... His profile represents a huge value in the eyes of sponsors and clubs, as well as in terms of shirt sales and media exposure.
"And all that, put together: ticket sales, TV rights, everything Erling will earn over the course of his career, I'm convinced it will exceed a billion."
