Real Madrid has its own way of recruiting players, and they are very smart about it. Because, they are aware that Real Madrid is the definition of "TOP brand equity". Just imagine, a player can willingly go to Real Madrid for free and postpone the contract extension with the old club. Just look at what is currently circulating with player Trent Alexander-Arnold, Real Madrid is reportedly very interested in the player because this is to strengthen Real Madrid's defense line.
That is only the goal of Trent Alexander-Arnold himself who really wants to go to Real Madrid because he really wants to carve out his career in the Real Madrid team other than in the Liverpool team like now. So we also can't assume all other players are like that because every player does have a certain goal during their career in a team even though every player knows that Real Madrid is a good team to defend. And if Trent Alexander-Arnold can dock at the Real Madrid team, of course Real Madrid's defense condition can be saved a little.
