Roberto Mancini angered by touchline spat with Lambert

Mancini clashed with Lambert during City's 4-2 Capital One Cup defeat.
"I am tired with these managers," said Mancini. "I didn't say nothing to him [Lambert]. There are some managers it is better to shut up.
"I asked only the fourth official if there was a yellow card, without moving my hands, and he comes over to me."

Mancini was upset by a tackle from Villa's Joe Bennett on City midfielder Gareth Barry, which led to his confrontation with Lambert. 

"I didn't speak with him," said Mancini. "I asked the fourth official if it was a yellow card because I thought the referee had forgotten his yellow cards in the dressing room.

"I don't know what is the reason. I can understand if I was talking to him but I didn't say nothing."
The Italian has had previous run-ins with Manchester United counterpart Sir Alex Ferguson, who accused Mancini of "haranguing the officials" during a Manchester derby.

City's boss has also been involved in spats with Everton coach David Moyes and Fulham manager Mark Hughes.

"I am very tired with their behaviour," added Mancini. "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 refused to get drawn into a slanging match with Mancini as he shrugged off the comments.

"If that's what he said then fine," said the Scot. "I respect him as a manager and an ex-player.

"It wasn't really a spat. It was nothing."

City twice led through goals by Mario Balotelli and Aleksandar Kolarov against Villa, who equalised each time through a Barry own goal and Gabriel Agbonlahor strike.

Charles N'Zogbia and Agbonlahor then scored in extra time to leave Premier League champions City without a win in four games.

"We don't play well and this is my fault because I am the manager," said Mancini. "Now I shall find the solution quickly as we have important games
.
"We can improve. We can get out of this situation by hard work."

He added: "Our problem is that we don't play very well and our play is too slow.

"It is the fourth [most important] competition clearly but we are disappointed because it is the only trophy I have not won."
