Manchester City lost their second game in a week against Aston Villa 4-2 in the Capital One Cup, and Roberto Mancini also lost his rag for the second time in a week.
After blasting Joe Hart for his emotional post-match interview in light of the defeat to Real Madrid, the Italian has launched an attack on Villa boss Paul Lambert after the pair had to be separated on the touchline on Tuesday night.
"I am tired with these managers," bemoaned Mancini in his post-match press conference.
"I didn't say nothing to him (Lambert). There are some managers it is better to shut up," he added.
Lambert's reaction had been provoked by Mancini complaining about Joe Bennett's tackle on former Villan midfielder Gareth Barry, who also scored an own goal to level the tie.
"I asked only if there was a yellow card - without moving my hands - with the fourth official 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."
Mancini has been criticised in the past by sections of the British press for waving imaginary cards; a trait deplored by English football purists. Although he appeared to suggest his nationality was instrumental in him occasionally rowing with fellow managers during games.
"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 were beaten by two goals after extra-time having twice lead their visitors at the Etihad Stadium.
