Defending champions City are 22 points behind current league leaders Liverpool.
Bernard said, "Liverpool haven't surprised me, they're one of the best sides in the world and we knew they were going to be strong this season.
"It's not just luck, they have a lot of merit but with the little details, everything went their way.
"In my first season here when we broke all the records and finished with 100 points, I remember winning three or four games in the 93rd or 94th minute and sometimes things go your way. Sometimes the ball that goes to the post and goes wide sometimes goes to the post and goes in.
