The City boss added: "The result is there, we congratulate Sporting for the game. We made a fantastic first half, then we struggled to score when we created, then we conceded when the opponents did not do much. Sometimes they can run, they can punish us a little bit, it can happen. But we have to avoid [what happened for] the third and fourth goal [both penalties]. Emotionally we were not stable enough, in this competition you have to be stable."
