THE FA will investigate Edinson Cavani after he used the word 'N******' on social media.
The Uruguayan scored twice to lead Manchester United to a 3-2 comeback win after they trailed 2-0 at Southampton.
But Cavani's reply to a fan on Instagram sparked a social media backlash - with some labelling his language as racist.
A fan posted in Spanish, which translated to: "I love you Matador!"
Cavani replied on his Instagram story: "Gracias N******!"
Manchester United refused to comment when contacted by SunSport on Sunday night, but believe the context of Cavani's post was affectionate, as is often its intention in South America.
He is now said to be aware that the word can be interpreted differently in the UK.
However, the Football Association are still set to investigate.
The word is the same that former Liverpool Luis Suarez said to United's Patrice Evra during their race storm at Anfield in 2011.
Suarez was given an eight-game ban and fined £40,000 by The FA, but later wrote in his autobiography that the word has a different meaning in Spanish.
