Manchester City midfielder, Yaya Toure, has admitted defending the Premier League title will be difficult, but vows to improve in the Champions League.
Toure, who recently ended speculation about his future following a summer full of controversy, believes Chelsea, Manchester United and Arsenal are City’s main rivals.
"We know the Premier League will be difficult but I am focused on Manchester City now," he told Sky Sports.
"We must try to retain the Premier League but we know it will be difficult.
"With Chelsea, Arsenal and (Manchester) United, it is going to be very difficult, very tight.”
The 31-year-old scored 20 goals in the Premier League last season but failed to guide his side far in the Champions League. However, he insists the Citizens want to improve on their European performances.
"Hopefully at the end of the season we will have the trophy but we have the Champions League as well. It is very important for the club and we have not done so well in the last two seasons,” he added.
"It is important we do better than last year and try to make the quarter-finals."
