And the former Genk star’s family still live in Spain, including his children.
Courtois has made no secret of his affection with the country, frequently revealing that he still speaks the language and watches Spanish television.
Upon his arrival back from loan in 2014, he took Petr Cech’s first-team place and has been a key part of two Premier League winning sides since.
But that has greeted rumours of a move to Real, who are reportedly looking to overhaul their squad this summer.
Keylor Navas is one star who could be moved on, and according to CalcioMercato the Chelsea stopper is prepared to wait until the end of his contract in 2019 to secure his dream move.
The Blues have been negotiating a new deal with the Belgium international but CalcioMercatoreport that he will turn down their offers.
They report he is “crazy” about a move to Madrid, and leaves the Stamford Bridge side in a precarious position.
Chelsea transfer chiefs must now decide whether to cash in on the unsettled star or keep him on another season and risk losing him for nothing.
Real have also been linked with Manchester United’s David de Gea and Roma’s Alisson, with the former believed to be their top priority.
