Everton boss Carlo Ancelotti is demanding more from Richarlison.
The Brazil international has scored just one goal in his last 12 Premier League matches and has only six for the season, two of which came against League One Fleetwood in the Carabao Cup.
"He has to be more focused, he has to sacrifice more and that is it. There is no other way that I know to improve," said the Italian.
"I think he is not in a good moment because the statistics talk. It is true that he was suspended for three matches and he had difficulties to reach his best level.
"I hope that he can reach his best level with sacrificing more and more focus. Work harder on the pitch. Harder.
"He is working hard on the pitch and working hard in training. He has to understand what he is doing. I think he works hard every day. He has to work harder."
