Thibaut Courtois has again said he would like to return to Spain one day, adding that he will reassess his future at Chelsea in summer 2018.
The Belgium international has been regularly linked with a move back to La Liga -- where he spent three years on loan at Atletico Madrid -- since replacing Petr Cech as No. 1 at Stamford Bridge.
Real Madrid emerged as his most likely destination last summer, but Chelsea are determined to keep the 24-year-old.
Speaking in an interview with Spanish newspaper Marca, Courtois said he still feels a strong connection to Spain, where he developed into one of the world's best goalkeepers.
"I consider myself half Spanish," he said. "I miss not just the club [Atletico] but Madrid and the country.
"Since the first minute, I fell in love with Spain -- the people, the way of life, the food. I have kept up the late dinners, the siesta, and most of the television I watch is Spanish.
"When I left Spain I had it very clear in my mind that I would return one day.
"I have a contract with Chelsea for three more seasons. In 2018, when I begin my last season, I will have to evaluate if it's better to renew or to leave."
Chelsea have made a promising start under new head coach Antonio Conte and are fifth in the Premier League table after three wins from their first five matches.
And despite his desire to return to Spain eventually, Courtois says he is enjoying life under Conte.
"He always thinks about football and tactically he is very strong," he added. "He knows what he wants from the team and through videos he ensures that we get his idea.
"With Conte we know that, provided we work, the games will go well. His plan is to play well starting from the back and that suits me."
