Mason Mount has signed a new Chelsea contract until 2024.
The 20-year-old England U21 midfielder spent last season on loan at Derby under new Blues boss Frank Lampard, where he scored eight goals in 35 games as the Rams reached the Championship play-off final.
Chelsea have now tied down the future of another academy graduate after agreeing a new deal with Ruben Loftus-Cheek to keep him at Stamford Bridge for a further five years earlier this month.
“It’s a massively proud moment for myself and my family,” Mount told Chelsea’s official website
“I joined this club at six years old and it was always my goal to play for the first team one day. I’m really looking forward to the coming season now and working hard to have an impact here at Chelsea.”
