Bellerin says he appreciated the leadership of Arteta when they were teammates.
"I'd only been at Arsenal for a couple of years, Mikel was one of the captains in the dressing room, he was part of this Spanish speaking group that we had and he really did look after me," he said in the documentary 'Unseen Journey'.
"When I was young, I was a bit naughty, started getting money, I started meeting girls, started going out, all these things that everyone does at that age.
"But not everyone has the responsibility that I had at that time, starting to play for Arsenal first team.
"He was like a big brother, when I did something wrong, he looked at me and I was like: 'Oh, I shouldn't have done that.' Sometimes you need people to be honest with you."
