Manchester City boss Manuel Pellegrini has urged his side not to make any mistakes if they are to make it through to the next round of the Champions Leagues.
The Citizens registered a very important 2-2 away draw on Wednesday night and will be favourites to progress in the competition.
And the Chilean wants his players to finish the job next week at the Etihad Stadium.
"I always say to the players it is a game of 180 minutes so we must be intelligent and not to make too many mistakes," Pellegrini said.
"We must finish this game at home but you must have the personality to play no matter what pitch we play on.
"Tonight we have got a good result and we must try to finish it at home but we are playing against a very good team.
"We started very well and tried from the beginning to score a goal because of the way we play we are not used to trying to draw.
"I always say that it is important to score goals away so we came here looking to score from the beginning.
"We made a couple of important mistakes that allowed them to score their first goal and unfortunately for us I think the second goal was a clear offside.
"Before that we made another mistake in giving away the penalty but if we want to win we can't make those kind of mistakes but the team had the personality to continue to try to win the game.
"It was a very good penalty save from Joe but it was one of our mistakes also because we could have cleared the ball before that."
