The tall striker was signed on loan from Monaco last week after obtaining a work permit, and the Spanish boss has talked up the talents of the Ivorian forward.
The Mirror quotes him as saying: "He is a very hungry footballer which, at this stage of the season, is very important. His size will give you the wrong impression of the way he is as a footballer.
"He is technically very gifted, he has a real understanding of the space and combination play around him and is really quick with his penetrating runs, he is a real athlete.
"All those aspects make us a little bit different because we haven't got that sort of player with that presence and height. He is a footballer who is going to bring us a lot."
Everton are currently sixth in the Premier League.
