The former defender is confident that he will continue to improve if playing regularly in the Gunners first-team.
The young full-back broke into the first-team squad last season, putting in a number of impressive performances for Arsene Wenger’s side during the enforced absence through injury of Mathieu Debuchy.
He is now firmly the first choice right-back in the side, having carried his fine form from last year into the current campaign.
It has been a rapid rise from the youth squads for Bellerin, and Dixon says the manner in which he has grasped the opportunity will have come as a welcome surprise to many observers.
“He’s taken his chance better than anyone thought,” he told arsenal.com.
“He got his chance through injury and he’s never looked back. He’s done way better than some people may have thought.”
Despite having been impressed by Bellerin’s performances so far, Dixon says there are still areas for him to improve.
This year is only the Spaniard’s second of senior football, meaning he still has plenty to learn in the game.
He does, however, look to have all of the assets required to be a top full-back in future, with his defensive and offensive display in a Champions League win over Bayern Munich testament to that.
And Dixon is a firm believer that he will continue to improve, saying that analysing his game shows how well he is doing.
“When you sit down and analyse his game on a weekly basis you see that he’s doing very well indeed,” he added.
“There are still areas of game that he does have to improve on but that’s only natural because he’s so young, but as long as he keeps learning - and being in the first team every week will help - he will continue to improve.”
