The 19-year-old Gunners defender has not forgotten his past.
Chambers has sometimes struggled at right-back but where he has, perhaps surprisingly, impressed is in central defence.
And the young England defender admits he owes a lot to Southampton, while he is also pleased to be working with two ex-Saints in Theo Walcott and Alex Oxlade-Chamberlain at Arsenal.
“I owe a lot to Southampton. They made me the player I am today. We were educated really well at the academy," Chambers told BBC programme Football Focus.
“I think I’ve settled in really well, that’s credit to all the players and staff, they’ve helped me settle. I’m pretty proud, especially to make my debut at Wembley [with England] with all the Arsenal boys there as well.
“It’s fantastic [working under Wenger]. He brings through young players. Obviously Alex and Theo came from Southampton like me. It’s been really great working under him.
“I want to go into training and games and learn everyday from it."
