The Football Association should conduct “a comprehensive and independent review” into Eniola Aluko’s claims against England boss Mark Sampson, says anti-racism campaign group Kick It Out.
The footballer, 30, has accused Sampson of “bullying and discrimination”.
Sampson, 34, has been cleared of wrongdoing by two investigations and vehemently denies Aluko’s claims.
But details given by Aluko in a BBC interview on Monday “throw new light on the allegations”, Kick It Out said.
The Chelsea Ladies player alleges Sampson made a “racist comment” about her family in Nigeria being infected with the Ebola virus. Sampson vehemently denies saying this.
The FA said the allegation arose in informal correspondence and was not included in Aluko’s subsequent complaint, or it would have been investigated.
A three-month independent investigation by barrister Katharine Newton did not uphold any of the complaints and cleared Sampson and the FA of any wrongdoing.
Aluko, however, has claimed the investigation and a previous FA inquiry were “flawed”.
The FA denies this and says Aluko, who has played 102 times for England, declined to respond to the Newton investigation.
She has not been picked by Sampson since making allegations against him as part of an FA cultural review into England management.
The FA has insisted the timing was purely coincidental as the review was confidential and anonymous.
But Aluko claims she suffered “victimisation as a result of me reporting discrimination”.
“The situation regarding this is now one of utter confusion with claims and counter-claims,” Kick it Out said, pointing out Aluko’s comments were contrary to what the FA was saying.
“Kick It Out urges the FA to undertake a comprehensive and independent review of the processes involved in the original complaint made by Aluko up to the final point of the independent investigation by Katharine Newton QC.
“This is so they can take on board any lessons learned, to remedy any deficiencies identified and to ensure it has an operational culture that treats any individual, whatever their background, equally, fairly and with dignity and respect.
“The FA must ensure a situation like this will never happen again in order to build trust, confidence and credibility.”
