The defender was reflecting on his breakthrough into the side and what he has learned about himself.
While Arsene Wenger has spent big in the last few transfer windows to bring in established stars such as Mesut Ozil and Alexis Sanchez, he has also had to rely on youth in recent years.
Last season, the long-standing boss had 11 players aged 23 or under feature for his side at some point, with Bellerin and midfielder Francis Coquelin the biggest success stories.
The Spanish full-back only made his debut last September, and he says he couldn’t have wished for a better group to have broken into.
“I don’t think I could have been in a better group to have my breakthrough season,” he told arsenal.com.
I had experienced players that helped me in every situation, then I had young players and I think we gave the team that fresh air. It’s important to have that mix in the team is something I feel really proud of.”
“I learnt so many things about myself”
The defender has also been busy reflecting on his breakthrough season at the Emirates.
The youngster was drafted into the Gunners first-team last season by Wenger when summer signing Mathieu Debuchy spent an extended period on the sidelines though injury.
Reflecting on his meteoric rise to prominence, he says he has learned a lot about himself, and especially how to deal with the added pressure of being a regular in the senior side.
“I learnt so many things about myself,” he added.
“I learnt how to deal with pressure. That was one of the biggest things. When you get thrown into such big games at such a young age, it’s difficult to deal with.”
