Chelsea youngster Jay Dasilva has signed a new contract with the Blues until 2021 and will now return to Charlton Athletic on loan after a successful spell with the Addicks last season.
The 19-year-old left-back spent the second half of the 2016/17 campaign at the League One club, making 10 appearances.
Most recently, Dasilva was captain of the England Under-19 side which was victorious in the European Championship final for their age group earlier this month. With Chelsea, he previously won the FA Youth Cup a record three times and also the UEFA Youth League twice.
Charlton were in dire need of a left-back and Addicks boss Karl Robinson confirmed two weeks ago that the signing of Jay Dasilva from Chelsea was imminent.
Dasilva will spend the rest of the season on loan with Charlton.
