The highly rated young defender has signed a new contract at the club until 2019.
Clarke-Salter, 18, has impressed with the youth teams and was included in Chelsea’s pre-season tours this year.
His strong performances for the club’s Under-19 and Under-18 sides has been rewarded with a new long term deal. Clarke-Salter has also played in every game of Chelsea’s victorious UEFA Youth League campaign, and has featured for England at Under-19 level.
After the number of first team chances given to Loftus-Cheek and Kurt Zouma, Clarke-Salter will know that if he can continue his progress he could be the next youngster to break into the first team.
