Arsenal have confirmed that Calum Chambers has signed "a new long-term contract" with the club.
Chambers joined the Gunners from Southampton in the summer of 2014, and has since made over 80 appearances for the London club in all competitions.
The 23-year-old had been linked with a move away from the Emirates Stadium this summer, but has now committed his future to Arsenal by penning a long-term deal.
"I'm delighted Calum has extended his stay with us. He played an important role last season and will be part of my plans this season," new Arsenal boss Unai Emery told the club's official website.
Chambers, who made 12 Premier League appearances last season, spent the 2016-17 campaign on loan at Middlesbrough.
