Manchester United match-winner Edinson Cavani risks FA investigation after using the racially insensitive slur on a social media post, the same as one used by Luis Suarez in the Patrice Evra statement.
The Uruguay international has since deleted the post but could be punished by the authorities.
The 33-year-old shared some of the positive messages he received from fans in the wake of the victory and responded to one post with the message “Gracias n******”.
The term Cavani used is the same Uruguay co-star Luis Suarez is said to have used during his altercation with Patrice Evra in October 2011, which resulted in the former Liverpool star being fined £40,000 and banned for eight matches.
Man Utd star Cavani
The Manchester United striker came off the bench to fire his side to a 3-2 win against Southampton on Sunday.
Manchester United were deep in trouble and 2-0 down to a confident Saints side when Cavani made his entrance at the start of the second half, although that entrance was delayed as he appeared to be wearing the wrong footwear.
Whatever he put on his feet certainly did the job – although most of the damage was inflicted with his head.
The Uruguay international came off the bench for the second half and set up Bruno Fernandes to pull one back before heading in two of his own to seal the three points deep in stoppage time.
Cavani’s pedigree cannot be questioned after scoring 341 goals in 556 club matches, including a record 200 goals in 301 games for PSG and 50 in 116 games for Uruguay.
The FA and United have not commented on the issue as of yet.
