Everton players Tim Howard, Joleon Lescott and Joseph Yobo reacted furiously when something was said whn Newcastle were awarded a penalty in Saturday's match at Goodison Park.
Although the Football Association originally said no action would be taken against Emre, they now want to interview Howard, who is understood to have complained to referee Dermot Gallagher.
Emre's agent Ahmet Bulut: "I spoke with Emre and he said that he never said anything racist to the player.
"His best friend at Newcastle is Obafemi Martins, who is black. These claims are not true. Emre never had any problems when he played in Turkey or Italy and he has never had any problems with other players in England either.
"On the field, he is an aggressive player, like other players are, but he would never make racist remarks. My English is bad, but his is even worse and he wouldn't even know these racist words."
