Alex Oxlade-Chamberlain says Calum Chambers is already part of the furniture at Arsenal.
The defender has been impressed with the way Chambers has settled into life at Emirates Stadium.
"People sometimes do not realise how difficult it can be for a young lad to come to a club like Arsenal and take the responsibility of playing centre half," he said.
"It is a massive thing and he has done it with ease.
"You would not know he is a young lad by the way he plays and the way he is on the ball. He has bedded into the squad really well and he is a great talent."
