The defender has enjoyed a solid first season since moving from Southampton last summer.
The youngster joined the Gunners joined from Southampton last summer and immediately impressed in both the right back spot and at centre half as well.
His often composed performances also led him to making his debut for the England senior team, going on to play three times for them, and he admits that the season and his personal performances, exceeded all expectations of what he thought he could achieve when arriving at the Emirates.
“In a short space of time I think I have grown massively,” he said.
"I have exceeded my expectations of what I thought I would achieve this season. Playing for Arsenal is an achievement and so is playing in the Champions League and for England. I am really proud of myself. I want to go further and become the best player I can at Arsenal. I won’t stop working until I get there.”
Chambers had previously developed at Southampton under former boss Mauricio Pochettino, but says the chance to work under Arsene Wenger was too good to turn down last year.
He has since upped his game under Arsene Wenger, who has a history of developing young talent, with fellow Saints graduates Theo Walcott and Alex Oxlade Chamberlain having also moved to the Gunners and stepped up.
Elsewhere the likes of Cesc Fabregas and Aaron Ramsey are also success stories for the Frenchman, and Chamber says he is glad he has been able to repay back his managers’ faith.
“He has been fantastic to me, really supportive and he has given me a opportunity to play,” he added.
“I can’t thank him enough. I think he is very thoughtful in everything he does and you know he gives everyone a chance and gets the best out of all the players, which is a very good quality as well.”
