Chelsea keeper Courtois already thinking of extending Atletico Madrid stay
"I know the club, the players and the coaching staff, and my Spanish is better," Courtois told El Mundo Deportivo.
"The first few months were tough and then I adapted well. I wanted to stay here another year. Chelsea knew that. I had no doubt in my mind, I was completely clear and very happy that is all came through as I wanted.
"It could be that Atletico ask me to stay another year. I am very happy here and if I stay for one, two or ten more years I will be very happy. I don't know what will happen."
