Bellerin scored an own goal but recovered to put in a brilliant display himself by setting up two goals as the Gunners ran out with 3-1.
The Spaniard, however, reserved special praise for goalscorers Mesut Ozil and Pierre Emerick-Aubameyang, as well as striker Alexandre Lacazette.
He said with the attacking talent at their disposal, they were always confident of making a comeback.
“It has been a difficult game and they put us in some trouble but we stood up and in the second half the football started flowing and found space in the game,” he told post match press conference.
“We have players like Mesut Ozil, Alexandre Lacazette and Pierre-Emerick Aubameyang and it’s easier for the goals to come.
“Leicester are a team that press on the front foot and have a lot of pace in the final third.
“It is hard to defend against and we knew we would have these problems.”
