David McGoldrick scored twice at the weekend.
Sheffield United have condemned racist abuse which was directed at striker David McGoldrick on social media.
Irish international McGoldrick scored twice in Saturday’s 3-0 win over Chelsea.
His club said they "will do all we can to find the perpetrator of this disgusting message.”
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.
