Chelsea youngster Charly Musonda has signed a new deal with the club, keeping him at Stamford Bridge until 2022.
The 21-year-old midfielder made his Premier League debut as a substitute on the opening day of the season and has five first-team appearances to his name.
He scored on his full debut for the club, a 5-1 win over Nottingham Forest in the Carabao Cup.
"I am very happy and very proud. I came here very young and am very happy to continue my journey here." Musonda told the club's website.
"I love this club so it's a great moment for me and my family. Now I want to establish myself and progress into the team and stay here permanently."
"We are very happy Charly has committed his future to the club," Club director Marina Granovskaia said.
"He is an exciting talent who we believe can develop into an important first-team player and we hope he will be a part of Chelsea's successes for a long time to come."
