Calum Chambers has grown up a lot since arriving in north London back in 2014.
The England defender joined us from Southampton as a fresh-faced 19-year-old five years ago and has amassed more than 100 senior appearances since, gaining vital first-team minutes on loan at Middlesbrough and Fulham.
Now back in London, Chambers is hoping to use those experiences away from the capital to establish himself as a key figure within Unai Emery's side.
"I've had a lot of experiences over the years like going to Middlesbrough and Fulham, and playing a few games here at Arsenal," he told Arsenal Player.
