Manchester City full-back Bacary Sagna admits the club suffered from over-confidence last season and revealed they are more focused this time around.
The 2013/14 Premier League champions surrendered the title last season without barely even a whimper, finishing eight points behind winners Chelsea, but have begun this season emphatically with five wins from their opening five games without conceding a single goal.
"The manager didn't have to say anything, we knew we didn't deliver and had a bad season," the France international told Sky Sports.
"We had a long season last season and it did not go as we expected because we got knocked out of the competitions quite quickly.
"Now we want to dictate the game and we want to change the pace of the team to change the pace of the game.
"When we have the chance to impose ourselves on our opponents we try and show them we are better. That has led us to first position today. We've managed to win five games out of five so now we want to keep that going.
"Maybe we were a bit too confident – we were stepping into the games a bit too comfortable. That's why we got punished because the other teams in the league have quality players."
The Sky Blues welcome an in-form West Ham side, who have already beaten both Arsenal and Liverpool away from home, to the Etihad Stadium on Saturday looking to make it six wins from six in the Premier League.
