Chelsea manager Antonio Conte accused Manchester United of deliberately targeting Eden Hazard during his side’s 1-0 FA Cup quarter-final victory.
Ander Herrera was sent off for two fouls on Hazard, while Marcos Rojo later appeared to stamp on the Belgian.
N’Golo Kante’s 51st-minute winner secured Chelsea a semi-final meeting with Tottenham at Wembley in April.
“In 20, 25 minutes for Hazard, it was impossible for him to play football,” said Conte.
“I see only that he got a lot of kicks. I don’t think that I’m crazy and I see only him in this situation.
“He started receiving kicks and finished receiving kicks. No one person can say this did not happen.”
