The Football Association are to write to Everton regarding allegations of racial abuse made by Newcastle United midfielder Emre.
Referee Dermot Gallagher mentioned the claims of the alleged abuse by the Turkey international in his match report following Everton's 3-0 home win over The Magpies, but did not hear the alleged comments himself.
The Toffees allege that the former Internazionale man racially abused Everton goalkeeper Tim Howard and defenders Joleon Lescott and Joseph Yobo, for whom the midfielder had angry exchanges with following the award of a Newcastle penalty in the game.
The FA confirmed they would investigate the matter further by speaking with the Merseyside club.
"We have received the referee's report and he mentions that an allegation was made, but he did not hear anything himself," said an FA spokesman.
"We will be writing to Everton to request any further information with which they can provide us."
Meanwhile, Everton have finally secured the services of midfielder Anderson de Silva on a six-month contract.
The Brazilian agreed the deal before Christmas and arrives after resolving ongoing passport issues that prevented him from joining the club at the start of last season.
The former Racing Santander player spent time on loan with Spanish club Malaga last term, but de Silva finally has the chance to make his mark with The Toffees for the latter half of the current campaign.
