Thibaut Courtois' agent has said he has held regular meetings with Real Madrid directors at which they "evaluate" the Chelsea goalkeeper's situation.
Madrid are reported to be keen to add a goalkeeper in the summer and Courtois, along with Manchester United's David De Gea and AC Milan's Gianluigi Donnarumma, has been linked with a move to the Bernabeu.
Courtois, who had a three-year spell on loan for Atletico Madrid, has previously spoken of the lure of a return to the Spanish capital, where his daughter and former girlfriend live.
Agent Christophe Henrotay told Belgium's Sport magazine: "Obviously the biggest clubs are interested in Thibaut, and that includes the reigning European champions.
"He is a goalkeeper who wins you games, wins you trophies.
"I meet regularly with Real Madrid's directors and Thibaut's situation is evaluated. My role is to keep him informed of the situation."
Courtois is under contract with Premier League champions Chelsea until 2019.
