Manchester City manager Roberto Mancini has no doubts that his side need to start scoring after their draw with Chelsea at Stamford Bridge on Sunday.

The Premier League champions endured a goalless draw with the Blues despite strikers Sergio Aguero, Edin Dzeko, Carlos Tevez and Mario Balotelli all being involved in the match.

"If want to win we need to be more strong in the box. We played very well. We dominated the first half, we are missing the last pass, the last assist," said Mancini.

"When we had a chance to shoot, we didn't shoot strong. If we scored one goal maybe we score two, three, but playing against Chelsea is not easy."

City travel to Wigan Athletic on Wednesday in their next Premier League encounter.
