Alfie Doughty scored his first goal for Charlton in the 3-2 win over Bristol City on Boxing Day
Charlton Athletic have exercised an option to extend the contract of Alfie Doughty until the summer of 2021.
The 20-year-old midfielder has made 16 Championship appearances since returning from a loan spell at National League side Bromley in October.
Doughty, a product of the south-east London club's academy, made his first-team debut for the Addicks in the League Cup in August 2018.
Charlton are in talks with the player over a further extension to his deal.
