Bellerin has become a stalwart of the Arsenal defence this season, and is already rated as one of the league's best right backs.
But the 20-year-old knows that he owes a lot to the London club and one coach in particular for making the player he is now.
"When I first came to Arsenal, I didn't know how to defend," Bellerin said.
"I have said it before, there is great depth in the team," Bellerin added.
"There are a lot of young players in the team waiting to come through, and we have a lot of quality training with us every day.
"They are ready to step up so obviously every single player on the bench can do the same job as every single player in the starting XI. We don’t need to worry about [the injuries to Alexis and Koscielny].
"The only thing we need to do is go out onto the pitch with the right mentality, it does not matter who we play."
