The former Atletico Madrid man has regularly been linked with a return to Spain and the Blues keeper is believed to be a target for Real Madrid.
The 25-year-old has a contract at Stamford Bridge until June 2019 and it seems he has his heart set on a move to Spain so he can be closer to his children, who are growing up in Madrid.
“A return to Spain is attractive for me,” he is reported to have told TV station La Sexta. “My own personal situation is the main driver for my desire to return and if that does not happen now, then it will in a few years from now.
“Right now I’m calm and happy at Chelsea, when you play football at this level you must concentrate only on the games and not on anything off the pitch.
“I don’t want to focus on contract talks as it will impact on my performances.”
