The player in question plays in a midfield or forward position and is not a Premier League player, according to Perez.
The Spanish giants are looking to make a statement signing this summer, with Perez describing the player as a "total Galáctico" and a "Cristiano Ronaldo or Kaká level player".
The club is set to be led by José Mourinho next season, and Perez believes that the player they are interested in will be a key part of the team's success.
The identity of the player is expected to be revealed in the coming weeks as fans eagerly await updates.
Several players have been tipped to meet Perez's requirements, including Jamal Musiala, Desiré Doué, Khvicha Kvaratskhelia, and Ousmane Dembélé.
