Roberto Mancini is adamant it is not in the DNA of Manchester City to concede defeat in the Premier League title race after Sunday's win over Chelsea.Mancini added: "In football, it is finished when it is finished: the last minute of the last game. I think our job is to continue to work. "We worked well this week. It was important to start well - be strong, don't concede anything." While the result may not prevent speculation over the Italian's future, it did not pile pressure on in the way defeat did for opposite number Rafael Benitez. Benitez's side were far from potent and the unpopular Spaniard was once again subjected to abuse from fans. He continued to put on a positive face and joked when asked if he was tiring. Benitez, who put John Terry and Fernando Torres on the bench, said: "I was not running so I am fine. I am disappointed because we could not win. "I am just thinking about the next challenge." Benitez agreed the game hinged on the penalty, but was unsure if Hart should have been sent off. He said: "I haven't seen the replay, but (it should have been) at least a yellow card. You can argue he is going in this direction but it is still a clear chance. "I think it was a turning point. It was a crucial moment in the game."
