Cesar Azpilicueta has completed a free transfer to Atletico Madrid to end his 11-year stay at Chelsea.
The defender had been a mainstay at Stamford Bridge since arriving from Ligue 1 side Olympique de Marseille in 2012, making over 500 appearances, scoring 17 goals, and winning every major title available.
Todd Boehly, Chelsea chairman, and Behdad Eghbali, co-controlling owner, said: "Cesar leaves an everlasting mark at Chelsea, as a warrior, as a champion, and as loyal Chelsea legend.
"He has set the standards at the club for more than a decade and demonstrated to everyone what is required day in, day out to achieve success."
The 33-year-old has joined Atletico Madrid on a one-year deal after Chelsea agreed to let their club captain go with 12 months left on his contract.
A Chelsea statement read: "Congratulations and good luck, Cesar. We'll be forever grateful."
