Joe Hart was the hero for Manchester City during the first half of their Champions League clash with Borussia Monchengladbach, saving a penalty to keep the scoreline at 0-0.
The Sky Blues should have taken the lead with five minutes on the clock when Raheem Sterling's low cross towards the back post found Sergio Aguero in front of goal, but Yann Sommer produced an instinctive block.
Gladbach had the opportunity to take the lead from the penalty spot in the 25th minute when Raffael was felled in the area by Martin Demichelis.
Raffael stepped up to take the kick himself, only to be denied as City goalkeeper Hart guessed correctly and saved it.
Hart had a string of additional saves to make before the first half was over, thwarting Raffael in a one-on-one situation in the 34th minute, before denying Patrick Herrmann from a tight angle to keep City level pegging at the interval.
