Manchester United have triggered a one-year contract extension for Tahith Chong.
The Holland U21 winger is currently on-loan with Birmingham City.
Chong was approaching the final months of his contract but United have taken up their option of an additional year to tie the winger to the club until 2023.
Chong has scored once and assisted two goals from 16 starts at Brum, having had his season interrupted by a four-month lay-off due to groin surgery.
He has not played for United since the Europa League last 16 second leg against LASK in August 2020 and he spent last season on loan at Werder Bremen and Club Brugge.
