The Norwegian striker has enjoyed a brilliant first season in the Premier League with Manchester City but the player's agent Rafaela Pimenta has hinted that he could move to the La Liga giants in the future.
City manager Pep Guardiola has previously denied reports that Haaland's contract with City has a release clause that will allow him to join Real next year.
Pimenta told the FT Business of Football Summit in London: "There's the Premier League and then there's also Madrid.
"They have something of their own that is also the dream for the players.
"Madrid keeps this magic going. They don't have the weekly competitions, but they have the Champions League."
Pimenta became Haaland's agent after her business partner Mino Raiola died last year and explained how she and her clients always "try to make a plan" about how they envisage their careers panning out.
She said: "We have to make a plan, we need to have a goal. Maybe we won't achieve it, but if we don't know where we're going, then for sure we don't get there.
"We make plans, yes, we make plans even if they are a 15-year-old. We cannot be sitting down and waiting."
Pimenta also revealed that she is surprised that playing in the Premier League is such a big attraction for players.
She said: "When I started in this business, if I tell them [a player], 'You move to England', they would ask me, 'What did I do wrong?'
"Now when we talk to players, and ask them what is their goal, they say the Premier League. They don't say a team, City, Chelsea, or Arsenal, they say the Premier League.
"This is the first time in 25 years that I hear so many players say I want to go to a league, not to a club."
