The Gunners increased their winning streak to ten last night with a 3-1 victory over Leicester City.
And speaking after the game, Bellerin said he was confident Arsenal were now used to how Emery wanted them to play.
"For us, it's always important to improve and keep things realistic," Bellerin told the club's website.
"It's a new season with a new manager and, of course, we're almost in November already, so things are getting a bit easier in terms of tactically and we know the way that the coach wants to play.
"As you can see on the pitch we're way more organised and the football flows a bit more, but as I've said, it's only the start and there's a lot of work we still need to do. Hopefully, the results are going to keep coming."
