England's Football Association said Friday it would investigate a newspaper report that Newcastle midfielder Emre Belozoglu had racially abused Bolton forward El Hadji Diouf.
Turkey international Emre, who is already subject to FA charges that he abused three black Everton players during a match in December, was reported by Friday's Daily Mirror to have used very strong racist language against Diouf during a Premiership match at Newcastle in October 2006.
The newspaper did not provide any source for its report, in which it claimed that Diouf had to be physically restrained from confronting Emre over the alleged insult.
An FA spokesman said the governing body would be asking Diouf about the Mirror's report.
"We will be looking into these allegations and will be contacting El-Hadji Diouf to see if he wishes to provide us with a statement," he said.
There was no immediate comment from Emre himself or Newcastle but the player's agent, Ahmet Bulut, insisted: "This is not a true story."
Emre last month denied a charge of "using racially-aggravated abusive and/or insulting words" during Newcastle's Premiership match at Everton on 30 December.
He was alleged to have made racist comments to Everton's goalkeeper Tim Howard, Joseph Yobo and defender Joleon Lescott.
The referee did not hear the alleged remarks but his match report included a mention of the fact that Everton players had complained to him about Emre's conduct.
Emre has denied the charge and asked for a personal hearing, for which a date has yet to be set.
