Reece James commits his future to Chelsea with new long-term deal
The 22-year-old right-back has made 128 appearances for the Blues after coming through their academy.
"I am over the moon with my new contract and I'm thankful for the fans, the new ownership and everyone involved in the club," James told Chelsea's website.
"I cannot wait to see what the future holds, and I am sure we will have the chance of winning many trophies.
"I grew up supporting this club and I've been here since I was a six-year-old. I put pen to paper on a new deal because this is the club I want to be at. We have a bright future ahead of us."
Chelsea chairman Todd Boehly said: "We are thrilled to give Reece a new long-term contract at Chelsea. He is an outstanding player and a true Chelsea man."
The defender had previously spent a season on loan with Wigan in the Championship during the 2018/19 campaign, but has developed into an England internation since returning to London.
