The defensive midfielder, who joined Chelsea academy at 8 and has scored four goals in all competitions for the senior team, has another chance of proving himself after French defender Wesley Fofona picked up a knee injury in the champions league clash against AC Milan in October.
Co-owners, Todd Boehly and Behdad Eghbali said: “We’re delighted that Trevoh will be extending his stay with Chelsea. He has been with us since childhood and has grown into an exceptional young player. He’s an important part of our men’s first team squad and we’re excited to see what’s next for Trevoh at Chelsea.”
Trevoh Chalobah said: “I’m really over the moon to sign this contract. I want to give my all and do anything for this club”
