Arsenal are reportedly lining up Southampton defender Calum Chambers as a potential replacement for Bacary Sagna.
The Frenchman is expected to leave the Emirates Stadium this summer, and Gunners boss Arsene Wenger sees the Saints youngster as an ideal successor, the Daily Mail reports.
Sagna is out of contract at the end of the season and has so far refused to sign a new deal, with Manchester City thought to be interested in recruiting him.
Chambers, 19, has made 21 appearances for Southampton this season.
