Portsmouth boss Harry Redknapp has accused Chelsea's Michael Ballack of diving after their 4-0 Carling Cup defeat.
Ballack went down in the area under a 36th-minute challenge from defender Nadir Belhadj.
Frank Lampard scored from the spot - the first of a double - to set the Blues on the way to a romp, with Salomon Kalou and Florent Malouda also hitting the target.
But angry Pompey boss Redknapp said: "He dived. That was never a penalty. I've seen it on video a dozen times.
"He left his leg in there and dived. It was a blow because we were sitting in there and thought we could have gone in 0-0 at half-time.
"Then all of a sudden you are 1-0 down and then it's 2-0. But we gave away some scandalous goals."
Pompey defender Hermann Hreidarsson was booked for a furious outburst at prone Ballack as the German skipper lay on the ground.
