The 20-year-old versatile defender left Southampton for North London in the summer for an undisclosed fee after a terrific campaign for the Saints last season.
He was soon integrated into the Gunners’ first-team squad, starting the Community Shield final in August before making his Premier League and Champions League debuts the same month.
His impressive early season form was soon rewarded with international recognition, first making his England debut in September before starting for the first time for his nation one month later.
It has been some ride for the former youth player, and speaking ahead of the Gunners’ FA Cup clash with Middlesbrough he admitted that his season objectives have already been blown out of the water.
“I set a few goals at the start of the season and I exceeded them massively so I’m really pleased," he explained.
“It was a whirlwind few months, it all happened so quickly I didn’t really have the time to sit back and think: ‘Wow, this is pretty good.'
“I just got on with it and tried to play as best I could in every game. It was an amazing few months getting my Arsenal debut, Champions League debut, England debut.
“I knew coming to a club like Arsenal there would be competition for places. I knew that at training every day it was going to be tough and that’s what I wanted.
“You can’t turn down the opportunity to come to a club like Arsenal. I wanted to rise to that opportunity and prove to everyone what I can do and how good I can be."
Chambers has started 14 Premier League fixtures this season, though his dream debut campaign at the Emirates has been slightly hampered with a succession of niggling injuries of late.
He last featured in the FA Cup victory over Brighton three weeks ago and it’s probable he will be included again against Championship promotion hopefuls Middlesbrough on Sunday.
