The 30-year-old goalkeeper, who saved two penalties in the Champions League final shoot-out win against Bayern Munich, has signed a deal to keep him at Stamford Bridge until 2016
The Czech international shot-stopper joined the Blues in 2004, arriving from French club Rennes for £9 million, and has gone on to make 369 appearances for the club, winning three Premier League titles, four FA Cups, two League Cups and most recently Europe's biggest club prize this season.
Indeed, the impressive figures don't end there, as, over the course of his Chelsea career, Cech has kept 178 clean sheets - representing a staggering 48% of his matches.
Speaking to Chelsea's official website, Cech said: "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."
The club's chief executive Ron Gourlay continued: "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."
