Arsenal defender Rob Holding has signed a new three-year contract with the Premier League club.
The new deal runs until 2024 with an option for a further year.
"I have been hugely impressed with Rob's contribution to the club and the dressing room, on and off the pitch," said Gunners manager Arteta.
"The quality of his work every day on the training pitches is excellent and he is translating this into consistently high performances in matches."
Former Bolton trainee Holding suffered a serious knee injury in December 2018, returning to first-team action almost 10 months later.
