Courtois is currently spending a third straight season on loan with Atletico Madrid but he is expected to return to Stamford Bridge in the summer after Jose Mourinho revealed recently that another loan spell was unlikely.
The 21-year-old's long-term future remains the topic of intense speculation, though, with Spanish radio station Cadena Ser reporting that Real are poised to snap him up.
It has been suggested that Real will sign Courtois on a free transfer in 2016 when his Chelsea contract expires, if they cannot convince the Blues to part with him at the end of this term.
However, Courtois' father has dismissed the latest rumours as an attempt to unsettle his son and Real's title rivals Atletico, telling the Belgian press that there have been no talks yet with Chelsea.
"It's an attempt to destabilise Atletico," Thierry Courtois is quoted as telling La Derniere Heure.
"There hasn't been any contact with Real. Our negotiations with Chelsea still have to start.
"And Chelsea would never let him go that way, when his contract has expired. Thibaut is now focused on the season with Atletico and the Champions League."
