That's according to Spanish expert Guillem Balague.
Courtois has 18 months to run on his current Blues deal but apparently wants to return to the Spanish capital at Real Madrid after spending three years at Atletico.
Writing in AS, Guillem Balague claims the goalkeeper wants to leave Chelsea and has already touted his services to Zinedine Zidane's side.
Chelsea are believed to be keen on a renewal, with Balague adding that they are prepared to make Courtois the highest-paid goalkeeper in world football.
But Antonio Conte is allegedly aware of the Belgian's desire to leave and would be prepared to sell him next summer for a mega-money fee.
