Some players find it difficult to refuse Real Madrid's request to come and play with them, it's not about the team with all the prestigious titles, but there are other extraordinary influences that can influence a player's decision. I think Perez had a big influence in bringing in the players he was targeting, some of them even left their old clubs for free. Many other teams have also won domestic titles, but their presidents do not have much influence. I'm really having a hard time figuring out just how big of an influence Perez is on this football, which seems to be so big.
Real Madrid is a very big club with quit alot of history in old and modern football, they're the best when it comes to Champions league trophy, that alone is enough to attract top players to the team, infact to lots of them, it's a privilege to play for the team, not all players would turn them down, it takes the likes of Yoro to do that and I believe that just 1 on 10 players would refuse Real Madrid's transfer offer many players would be wiling to wait till their contract expires just to make sure they switch to Real Madrid, that's how big the club is, luckily for those players Madrid's club president is some that really got the interest of the club's success at heart, he'll do anything to be sure Madrid succeed.
