Manchester City manager Roberto Mancini has urged his players to stop allowing their Champions League opponents as many chances as they have been.

Joe Hart made numerous saves in City's last Group D encounter with Borussia Dortmund, which is what Mancini is looking to avoid in future games, starting with Ajax on Wednesday night.

"We played against Real in Madrid, so it is difficult not to concede chances and it's important not to concede a lot of shots in Europe," Sky Sports News quotes Mancini as saying.

"We had a bad game against Dortmund but it is important we don't give away so many chances to score.

"People think it will be easy on Wednesday but Ajax have a good young team and will play well. It is more difficult away from home."

City are currently third in Group D with one points from two games.
