Full-back Bellerin made 28 appearances and scored twice in his breakthrough campaign last term and started in the FA Cup final at Wembley as Arsenal brushed aside Aston Villa 4-0.
“I’ve had a few people talk about second-season syndrome but I really don’t believe in it,” he told the club’s official website. “I think after a breakthrough season, what you have to do is keep going from where you left off.
“I’ve got the confidence knowing I’ve played 30 games already so I’m more confident in the games.
“It can always go both ways, it’s very difficult in football to always perform at your best level. You’re going to have ups and downs but that has got nothing to do with the first or second season.”
Bellerin is currently the first-choice right-back for the Gunners, having displaced France star Mathieu Debuchy last season and he is relishing the battle for places this term.
“I think the competition in every single position in the team is really strong. That’s going to make the team train harder, perform better and grow as players.
“We have to give our best. We know we can’t relax, we know we can’t take our starting position for granted when we have it.
“I think it’s very good and all the successful teams have that kind of battle in every single spot because that keeps you on your feet and makes you perform better.
“Even when you think you’re going to play you need to train hard because otherwise it’s on to the next one and you’re going to be on the bench,” the Spain U21 international said.
“I know it’s going to be difficult with Mathieu back now but I’m just going to keep training hard,” added the 20-year-old.
