Reece James wants to dedicate his "peak years" to Chelsea after signing a new six-year contract at Stamford Bridge.
The club captain's previous deal was set to expire in 2028 but the Blues have headed off any risk of his contract entering its final stages with an extension that will keep him at the club until he is 32.
An academy graduate who first trained with Chelsea at the age of six, James has made 225 appearances in all competitions since making his debut in 2019 and was appointed skipper in 2023.
The England international has lifted five major trophies with the Londoners, including the 2021 Champions League, but feels his best is still to come.
"I am over the moon to have extended my contract - Chelsea means so much to me," he told the club's official website.
"I have always said I want my peak years to be here, and I truly believe we have everything it takes to build on our previous successes. I'm excited for the future under this ownership, sporting directors, coach and all the staff and hopefully we will lift many more trophies together over the coming years."
The current season has been James' most fruitful in terms of minutes on the pitch after injuries to his knee and hamstring wrecked much of the previous two campaigns.
Chelsea, who face Newcastle live on Your Site on Saturday (kick off 5.30pm), have been extremely careful about how much time he spends on the pitch and have employed a carefully regimented model to ensure he is not overstretched. He has played 35 times in all competitions this season, his highest tally since 2021/22.
Kyle Walker touted him as England's number one right-back in a crowded field when he announced his own international retirement this week, hailing him as a "complete" player.
Chelsea boss Liam Rosenior couldn't hide his delight at the news of James' deal, describing the defender as "the best player in the world in his position".
"I can't stop smiling because we have secured the best player in world football in his position.
"He had many opportunities to leave this magnificent club and the good thing is not just the size and stature of the club but he's come through from a very young age, places belief and confidence in what we're doing, where want to go.
"We've had many conversations about it and for him to sign the deal and put his faith in us is a massive deal."
Rosenior added: "For as long as I'm here, he will be my leader.
"It's been a really good two and a half months with him. He's going to go on to have hopefully a really successful career at this club."
Sporting directors Paul Winstanley and Laurence Stewart added: "On behalf of ownership and everyone connected to Chelsea, it is a proud moment for all of us to have Reece extend his contract.
"He is the leader of this team, both on and off the pitch."
