Kolo Toure admits it will be difficult for Manchester City to defend their Premier League crown, but insists they are up to the task.
Toure spoke to Sky Sports NewsHD as City continue their pre-season tour of the Far East.
Having won the title with Arsenal in 2004, he was unable to help them win the league the following year, so the Ivorian stopper knows the task that awaits Roberto Mancini's men.
"It will be difficult defending because every team will come down and look to beat us," he told Sky Sports NewsHD.
"But when you're champion you need to behave like a champion and take it game by game.
"The confidence is here, everyone now just wants to win and when you win once you want to win every time and City now wants to win every season.
"We know how to win and now we have to work hard and give 100 per cent every game, the Premier League is the hardest in the world and five or six clubs could be champion and for us we will just focus on us and do our best."
