Manchester City boss Roberto Mancini knows his team needs to improve after drawing 1-1 with ten-man Stoke on Tuesday night.
City needed a late goal from Gareth Barry to savour a point and although Mancini admits things were not made easy for his team early, he insisted they must perform better, especially when there is a one-man advantage.
"In the first half it was difficult for us because the ball was always in the air," he said.
"But we fought very well and in the second half when we played with one player more we managed to play better.
"It is two (points) lost because we played 11 against 10 for 40 minutes. We must play better.
"We had many chances to score a goal but when we arrive in the box we must be more aggressive. You must have a chance and you must score a goal.
"I am disappointed with this result because when you play 11 against 10 you must play better."
