Manchester City great Yaya Toure believes manager Pep Guardiola won't allow complacency to develop this season.
City go into the new campaign as Treble champions.
Toure, who won the Treble with Guardiola at Barcelona, told the Daily Mail: "We won everything and then we had a bit of a downfall.
"But that is normal for human beings, you have to have the right motivation. Sometimes it is the leader, the head coach, who has to set this up for all the players.
"The coach said we are fighting against us. We are the problem, not the opponent. We tried to put the same commitment and desire in again, because it is not easy to repeat.
"It will be difficult but City already have the experience of winning the league year-after-year.
"The core of the team will also stay the same, they are still young but they have players with experience and a love of winning games week-in, week-out."
