Bellerin is confident that Arsenal will soon benefit from Emery's detailed approach.
He said: "I am impressed with Emery. We lost our first two games but we were very close both times. After the match, the players could feel that things were coming together. With Arsene, he wanted us to play in the same way regardless of the opponents. The idea was that we could play in our way and beat anyone.
"But Emery is very focused on preparing a plan for our next opponents, whoever they may be. It is very detailed and very professional. The next few months are going to be very exciting for all of us. We will reach a higher level."
