Calum Chambers has signed a new long-term contract at Arsenal, the club have announced.
The 23-year-old made 24 appearances for the Gunners last season and has been handed a fresh deal ahead of the new campaign.
Chambers will be hoping to impress new boss Unai Emery during pre-season as he fights for a regular starting place for Arsenal, who confirmed the signing of defender Sokratis Papastathopoulos from Borussia Dortmund on Monday
"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," Emery said.
Chambers arrived at the Emirates from Southampton in 2014 and has made 83 appearances in all competitions.
He spent the 2016-17 season on loan at Middlesbrough but could not help them avoid relegation back to the Sky Bet Championship.
