Manchester City manager Roberto Mancini has slammed fellow Premier League bosses and says that he is tired of their behaviour.
The Italian was involved in a confrontation with Aston Villa boss Paul Lambert during his side's 4-2 defeat in the Capital One Cup on Tuesday night.
Mancini has clashed with numerous opposing managers since taking charge of the Premier League champions and he thinks that some chiefs need to just "shut up".
"I am tired with these managers," said Mancini. "I didn't say nothing to [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.
"I didn't speak with him, 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."
"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."
City travel to Fulham on Saturday in the Premier League.
