Heroic Hart happy with point

Hart produced a string of outstanding saves to frustrate the German champions until Marco Reus finally broke through, after swooping on a poor pass from Jack Rodwell, after 62 minutes.

City looked set for back-to-back defeats to start their Champions League campaign until they were awarded a contentious late penalty, which Mario Balotelli converted.

"We've got to be happy with a point," Hart told Sky Sports 1.

"I thought Borussia Dortmund were different class tonight. It took a good defensive effort to keep it at one.

"The pass was a bit short and they took the chance.

"They were getting chances with four and back or even 10 at back. They were always going to get chances.

"For them to be the seed four team shows what a group we're in."

Hart's performance drew praise from his England team-mate Wayne Rooney who labelled him the best goalkeeper in the world during the match on his Twitter page.

Rooney wrote: "Have t o say joe hart has been incredible. For me best keeper in the world."

City boss Roberto Mancini admitted Hart had saved his side from conceding a hatful of goals and questioned his side's desire to compete against Europe's best.

"I think that Joe saved us. He did very, very well," he said.

"Today we deserved to conceded three or four goals. We didn't play well.

"We didn't play well because Borussia Dortmund played better than us.

"They probably at this moment are a better team than us. If we want to play in the Champions League we have to play better than tonight.

"We have to run and fight. It's not enough to just pass. Champions League is another situation - different from the championship.

"We have to run and fight. It's not enough to just have quality."

Mancini admitted his frustration as City remained without a clean sheet this season, but the Italian revealed he had identified the reason for his side's poor defensi ve performance tonight as they were over-run by Dortmund's fleet-footed young stars.

"We did a lot of mistakes. It was very strange for us," he said.

"I know the problem and I will resolve very quickly this problem."

Asked what the problem was, he added: "It is my problem. It is my job. I understand the problem and I will resolve (it) very quickly."

City's penalty lifeline came after Dortmund defender Neven Subotic saw Sergio Aguero kick the ball on to his hand at close quarters, a decision Mancini agreed could have gone either way.

"He touched the ball with his hand. He was unlucky," he said.

"It could be maybe not, but I'm happy with the penalty.

"I think in the end this point could be important."
