It’s a ridiculous desire to get a young super soccer player (who probably represents the future golden generation) for little money

This is something of a fantasy. Even if Haaland becomes a free agent it won't be cheap to get him - too many clubs want him and will give him huge payoffs for him to choose their club.
He has a release clause that is worth around 70-80 million euros.
Haaland's next buyers will have to pay out that amount plus a large commission for Raiola and Haaland's father.
I remind you that the player did not cost only 40 million for Borussia but 40 million plus 20 million for Raiola and 25 for Haaland's father for a total of 85.
So it will probably be an operation that will take place in June for a total value of 125-130 million.
