Fulham manager Mark Hughes was incensed after Manchester City counterpart Roberto Mancini's reaction at the end of the 1-1 draw at Eastlands.
Mancini only offered the limpest of post-match handshakes, not even bothering to look Hughes' way, triggering an angry reaction from the Welshman.
"I am old fashioned," he said. "I always think you should offer your hand in whatever circumstances, no matter how difficult it is.
"I did it, and did it with sincerity after my team had been beaten 4-1 at Craven Cottage earlier this season. I acknowledged his team were better.
"Maybe I misread it but I don't feel Roberto really acknowledged the efforts of my team and what we had done by the manner he offered his hand, by not looking at me."
Mancini countered with the accusation Hughes had done exactly the same thing in November following one of City's best performances of the season.
"In London he did the same," said Mancini. "I know he said something but I couldn't understand what.
"For you (journalists) it is maybe the best thing in the match, for me, no. It is not important. He (Hughes) should be happy. His team got a draw against us."
The City boss had earlier warned Mario Balotelli he cannot expect his work to be done once he has scored.
The controversial striker scored his ninth goal of the campaign at Eastlands yesterday but it was not enough to give the Blues victory.
Damien Duff equalised just after half-time and the Cottagers were more likely victors the longer the match went on.
And Balotelli was amongst those taking the blame.
"I am not happy with Mario," said Mancini. "I know him very well and I know he can play better. He can play for the team.
"He scored a fantastic goal but there were still 70 minutes left. He can't lose the ball all the time. Every time the ball went to the front, we didn't keep it."
