Manchester City boss, Manuel Pellegrini said that Joe Hart saving Lionel Messi's injury-time penalty gave City a chance to keep their Champions League hopes alive.

Luis Suarez scored two for Barcelona in the first half of the match, with Sergio Aguero clawing one back in the second half.

Pellegrini was unhappy with his team's performance in the first half.

"I think that we played two different games: the first half and the second. Until the first goal it was a very normal game and after that we concede an easy goal and played very bad until the first half finished. In the second half I think we played well, we scored one goal and had two or three more chances to draw," he said.

The City boss talked of the importance of Hart's save, after Pablo Zabaleta conceded the spot-kick.

"We finished with the penalty Joe saved very well. It was a very important save. Of course it gives us more chance to try to win in Barcelona; 3-1 [would have been] a very difficult score to try and erase. It was a very unnecessary penalty," he added.

The Chilean added: "It is not the best result to lose at home, but we will go to Barcelona to try to win. We still have the chance to do it."
