Show Racism the Red Card in Ireland and England have joined together with the Professional Footballers Association of Ireland to support James McClean, calling on the English FA to investigate all incidents of anti-Irish discrimination.
McClean yesterday highlighted what he believes to be unfair treatment based on his nationality and religion.
Today, the three bodies have released a statement, appealing to the FA to take action.
It read: "This statement is a joint call from Show Racism the Red Card Ireland, Show Racism the Red Card UK and the Professional Footballers Association of Ireland to both the Football Association in England and the Scottish Football Association to have a more robust approach to abuse faced by players like James McClean and managers such as Neil Lennon.
"Racism on the basis of colour, nationality, religion or ethnicity is not acceptable and all within the game have a responsibility to respond appropriately.
"James McClean has stood in solidarity with team mates who have experienced racism and spoken out. We stand in solidarity with James McClean, Neil Lennon and all those who experience racism.
"We call on both the Football Association in England and the Scottish Football Association to investigate all incidents of anti-Irish discrimination.
"We also call on both associations to invest funding in anti-racism education to help both supporters and young people understand the dangers and the impact of racism."
The statement is signed by Garrett Mullan (SRTRC Ireland), Stephen Mc Guinness (PFA Ireland) and Ged Grebby & Paul Kearns (SRTRC UK).
