Chelsea has "commended" Eniola Aluko for "speaking of her experiences" after she accused England boss Mark Sampson of "bullying and discrimination". Sampson, 34, has been cleared of wrongdoing by two investigations and vehemently denies the claims made by former England forward Aluko, 30.
But anti-racism group Kick It Out says the Football Association should conduct "a comprehensive independent review.”
It says claims by Aluko on Monday "throw new light on the allegations".
Speaking to the BBC, the Chelsea Ladies striker claimed 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 Chelsea spokesman has said the club "finds any and all forms of discrimination abhorrent and it is imperative that players are supported when coming forward to speak about these issues".
Aluko was supported by former England team-mate Lianne Sanderson, who tweeted: "I am so proud of one of my best friends, Eni Aluko. I have stood with you through this and I will continue to do so."
Former FA director of corporate affairs Simon Johnson tweeted: "Well done to Eni Aluko for speaking out. No-one should have to justify why they perceive a comment as racist. Sad it came to this, but brave."
A three-month independent investigation by barrister Katharine Newton last year did not uphold any of Aluko's 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".
