Chelsea have announced defender Cesar Azpilicueta has signed a new four-year deal.
The Spain international arrived at Stamford Bridge from Marseille in 2012 and will remain at the club until 2022.
The 29-year-old told the club's official website: "I am really happy to extend my stay here at Chelsea.
"Since I came, I felt the joy and responsibility to play for this club, these fans, and every time I go on the pitch I try to do my best.
"Hopefully there is a lot to come and we can keep Chelsea where it belongs."
