Fergie said there would be questions in Parliament if his team got as many spot-kicks as City.
But the Etihad boss hit back, claiming United dive to get their penalties.
Mancini said: “I remember last season when Ashley Young was swimming.
“Ferguson is probably saying it deliberately. He is clever. I think they had four or five pens in the last 10 games — then he didn’t say anything.”
In fact, United have been awarded exactly the SAME number of penalties as City over that period — although City scored 18 times to United’s 14.
And last season United were awarded 11 penalties — three MORE than City.
