Chelsea goalkeeper Petr Cech has signed a new four-year deal at the West London club, which will see him through to the end of the 2015-16 Premier League season.
Cech, 30, joined the club in 2004 and is already Chelsea's record appearance maker for an overseas player, having playing 369 times for the Blues, winning three Premier League titles, four FA Cups, two Carling Cups and a Champions League title.
"I am really happy to be part of this great club for another four years. I hope the next four years will be as successful as the last eight years I have been at the club," Cech said.
The Czech stopper played a key role in Chelsea's triumph in the Champions League this campaign, saving a penalty from Arjen Robben in extra-time to keep his side in the game.
Chelsea chief executive Ron Gourlay added: "Chelsea fully appreciates the highly significant contribution Petr has made to the most successful period in the club's history, and it is very important to our aim of continuing this level of achievement that he has committed himself to the club until 2016.
"It is clear to anyone who watched the climax to the season just completed that Petr continues to perform as well as any goalkeeper in the world.''
Over the course of his Chelsea career Cech has kept 178 clean sheets for the club, 48% of the games he has played.
