Arsenal boss Arsene Wenger has defended the form of Calum Chambers.
Wenger admits Chambers, who signed from Southampton during the summer as a right-back who can cover centre-back, has been overplayed due to the injury crisis that has thinned Arsenal's defensive options.
"For a 19-year-old, he has played too many games. They all hit the wall after 15 to 17 games. You have to give them a breather, let them refresh and get them back again," he said.
"To have that responsibility in every single game is a lot for a player of that age."
