Midfielder Joe Cole has signed a new four-year contract with Chelsea.
Cole arrived at Stamford Bridge in August 2003
The 24-year-old's previous deal was due to run out at the end of next season but he finalised new terms while with the England World Cup squad in Germany.
"The team spirit at the club is fantastic and there was never any doubt in my mind that we would agree a new contract," said Cole.
"I'm delighted we have got everything agreed so quickly and I'll be staying at Chelsea for the next four years."
Cole was signed by Claudio Ranieri in August 2003 for £6.6m, one of the first arrivals of the Roman Abramovich era.
When Jose Mourinho took over from Ranieri, Cole initially struggled to win a place but has since played a crucial role in Chelsea's title wins.
Blues chief executive Peter Kenyon said: "The club is naturally very pleased we have agreed a new deal with Joe.
"In our two Premiership-winning seasons he has been one of our best players.
"Last summer when contract talks first started he said he wanted to put it on hold for another year because he was confident he'd prove to us, through his performances, that he was worth a new deal. He has done that."
