Courtois spent three seasons on loan at Atletico from 2011 to 2014, but he is not thinking about returning to Spain.
When asked if he will be in Madrid – without Atletico or Real specified – next term, he told Onda Cero: “No. Right now I am enjoying the success here and I am focused on that.
“I have spoken English since I was 10 years old.
“I’m really enjoying myself here [at Chelsea] and I’m focused on finishing the league and winning it.”
