Yaya Toure says Manchester City must make amends for their defensive lapses against Real Madrid when they return to Champions League action against Borussia Dortmund.
The Blues were minutes away from a famous win in the Bernabeu, only to see Jose Mourinho's side claim all three points with two goals in a dramatic finale.
The Ivorian midfielder knows what it takes to win Europe's elite club competition, having done so with Barcelona, but City have a tough task to progress to the knockout phase for the second year in a row.
The Blues exited the competition despite accruing 10 points last season, with Napoli and eventual runners-up Bayern Munich moving on at City's expense.
Now they face the German champions, no strangers to the Champions League and winners in 1997, and Toure says City are in for another searching examination of their European credentials
"We are playing our first game at home and we want to show the fans we made a mistake in Madrid. We have a tough game against Dortmund," he said.
"Of course we need to improve when you play against a tough team like Madrid, we need to improve in defensive situations.
"We have to go beyond that and do better. Most important we have to do our job and get a result."
Toure feels the kind of experience he and other squad members have from greater exposure to the Champions League must be used when City face Dortmund on Wednesday.
"I have that experience and it is good to have big players like Maicon and Balotelli. It is not easy to win the Champions League," he declared.
"Here the club just wants to be in the second round and we know we have to improve because we have a very good team and with a team like this we can go very far in the competition."
