Southampton boss Ralph Hasenhuttl accused Everton striker Richarlison of diving in Thursday's 1-1 draw at Goodison Park.
Hasenhuttl was referencing Jan Bednarek's challenge on Richarlison in the second-half, which saw the Pole concede a yellow card.
He said: "I think, for me, it was only clear that he plays the ball.
"I can't understand why this is a foul. With him, he goes quick down on the ground and we have to handle this.
"We didn't give him a lot of chances."
The Austrian added: "I have never seen an Everton side struggle so much like this here at Goodison."
