Watford striker Troy Deeney could be in hot water after he seemingly swore at supporters as he celebrated scoring the opening goal against Chelsea on Monday night.
The Hornets were awarded a 42nd minute penalty after Gerard Deulofeu was brought down by Thibaut Courtois and Deeney stepped up and fired his side ahead.
The 29-year-old was being jeered by Chelsea fans as he prepared to take the penalty but, once he had converted from 12 yards, ran off the other way with both of his middle fingers in the air.
Fans have already urged the Football Association on social media to take action against Deeney and it remains to be seen whether they will hand him a punishment.
