Last week's shock defeat to Norwich has left City playing catch up in the opening weeks of the season.
"We accept it," he said. “It doesn't happen many times in the big moments. I'm relaxed. It's going to happen.
“There are 99 points to play for. We're five behind, but let's see how many we get. I lost many times as a player and a manager, the only way to survive here is to win games and we've won a lot.
“Many times we look to improve. You have to understand what we have done in the past.
"I've said many times, the strongest opponent we've had in Liverpool. I said when they were in front (last season) they have everything in their game, set pieces, transitions. I know how difficult it is and was and will be. That's the challenge."
