Petr Cech has committed his long-term future to Chelsea by signing a new four-year contract with the club.
The long-serving goalkeeper, who has made 369 appearances for the Blues since joining back in 2004, will stay at Stamford Bridge until 2016.
"I am really happy to be part of this great club for another four years," said the 30-year-old.
"I hope the next four years will be as successful as the last eight years I have been at the club."
Cech, whose original deal was due to expire next year, has been a key player for Chelsea.
He has helped the club win the the UEFA Champions League, three Premier League titles, four FA Cups and two Carling Cups.
Last season he was voted Chelsea's Player of the Year.
"Chelsea fully appreciates the highly significant contribution Petr has made to the most successful period in the club's history," said Chelsea chief executive Ron Gourlay.
"It is clear to anyone who watched the climax to the season that Petr continues to perform as well as any goalkeeper in the world."
Highly-promising Belgian goalkeeper Thibaut Courtois could act as understudy to Cech next season, having impressed in a loan spell at Atletico Madrid, although the 20-year-old is likely to make a temporary switch elsewhere once again.
Courtois, who joined Chelsea from Racing Genk last July, kept a clean sheet to help the Spanish side win the Europa League earlier this month.
