Jordan Cousins has signed a new four-year contract at Charlton Athletic.
The 21-year-old came through the youth ranks at the club, and made his Addicks debut in 2013.
The midfielder won Charlton's Player of the Year award last season after making 47 appearances, scoring three goals.
Cousins told the club's website: "It's a good feeling to secure my future. It's been talked about all summer and I'm pleased we could get everything sorted before the new season starts.
"I've been here for a very long time and I'm proud to come from this academy. It's my home, I feel part of the club and I want that to continue."
Cousins has made three appearances for England Under-20s.
