Manchester City manager Roberto Mancini tells rival managers to shut up, like they do at Manchester United I don't know what is the reason. I can understand if I was talking to him but I didn't say nothing. Mancini added: "I am very tired with their behaviour. Sometimes these managers go to the big stadiums and the other manager says everything and they say nothing. When they go to Old Trafford, they say nothing. When other managers talk about the referee they always sit on the bench. I don't like this type of behaviour. Lambert brushed aside Mancini's complaints, saying: "If that's what he said then fine. I respect him as a manager and an ex-player. It wasn't really a spat. It was nothing. Mancini may well have been trying to deflect attention from his side's third-round exit, having reached the semi-finals in two of the last three seasons. Despite making 10 changes from Sunday's 1-1 draw with Arsenal, the City boss was still able to field a team with combined value well over £150 million, even with teenagers Abdul Razak and Denis Suarez in the line-up. However, they twice threw away leads given to them by Mario Balotelli and then Aleksandar Kolarov after Villa old boy Gareth Barry's own goal had made it 1-1. Gabriel Agbonlahor took the tie to extra time and added a second after Charles N'Zogbia had put Villa ahead for the first time. "It was a difficult match because Aston Villa were a good team," added Mancini. We didn't play well and we had some unlucky moments but I think they deserved to go through. Lambert, in his first season at Villa Park having taken over in the summer, was delighted with the performance. It is a massive result for us. I thought the way we played was excellent," he added. It was a brilliant response from the team. It was a huge effort. We didn't deserve to go a goal behind but we showed real character to come back.
