The goalkeeper, who won plaudits for his performance in keeping the German champions at bay, is adamant that his side's late equalizer must spark qualification from their groupManchester City goalkeeper Joe Hart warned that his squad must not waste the lifeline given to them by Mario Balotelli's late penalty to draw 1-1 with Borussia Dortmund in the Champions League.
The English goalkeeper's brilliance had kept the hosts in the game as the German champions attacked with intent and Neven Subotic's handball in the area prompted the spot kick that Balotelli converted to provide Roberto Mancini's men with their first point of the group stage.
The Premier League side still lag three points behind Dortmund and five behind group leader Real Madrid, and Hart told Sky Sports that he hopes the equaliser "wasn't a wasted effort."
"I hope the effort we've made in both Champions League games hasn't been wasted, we're focused on qualifying from this group. But, as you can see, for the [lowest-seeded] team, it shows what a group we're in."
Hart was the other hero of the game and admits he has never made so many saves in one match.
"Unfortunately I didn't stop all of them, I would have liked to but Dortmund were different class tonight and it took a good defensive effort to keep it to one," he said.
A second-half substitution briefly changed City to a three-at-the-back system, during which time Marco Reus seized upon a Jack Rodwell error to score, but the goalkeeper does not feel that the formation was to blame.
"They were getting chances whether it was four at the back or 10 at the back or one at the back," he insisted. "I think they were always going to get chances.
"Unfortunately the pass was a bit short and he took the goal well. And we've moved on and Mario was called on and took his goal well."
