Calum Chambers is delighted to be reunited with Theo Walcott at Arsenal.
Chambers recalls facing Walcott at Southampton when he was just 10 years old.
"At the age of seven Southampton came in for me, and I went to play at the development centre," Chambers said.
"I just went along with it and enjoyed every moment.
"I trained with Theo Walcott at Southampton when I was about 10. He was on the wing against me.
"At that age, I was looking up to him and just hoping I could be as good as him."
