The FAI and Sheffield United have condemned racist abuse which was directed at Republic of Ireland striker David McGoldrick on social media.
McGoldrick, who scored twice in Saturday's 3-0 win over Chelsea, shared a screengrab of a message he was sent in which he was referred to by the n-word and told his life "defo doesnt matter!".
A United tweet said: "As a club we will support David McGoldrick and will do all we can to find the perpetrator of this disgusting message."
United added: "We will work with the relevant authorities to ensure the person behind this post is brought to justice.
"This cannot continue. Something needs to change."
The FAI has added their voice to the condemnation saying racist abuse could not be tolerated.
An FAI spokesperson said: "The Football Association of Ireland condemns the online racist abuse aimed at our striker David McGoldrick and joins Sheffield United in offering David all the support we can give him at this time. Such behaviour is appalling and cannot be tolerated by football or society."
It comes a day after West Midlands Police arrested a 12-year-old boy in relation to racist abuse sent to Crystal Palace forward Wilfried Zaha on social media.
The two goals by McGoldrick at the weekend marked the first time the Irish international had scored at Premier League level since Sheffield United's promotion.
