Emmanuel Frimpong allegedly ranted at Tottenham fans as he was substituted in Wolves's 1-1 draw with Spurs on Saturday.
The midfielder, on loan at Wolves from Arsenal, directed an insult towards Spurs fans after he was booed on his approach to the dugout, according to The Sun.
The 20-year-old later mocked Spurs online, tweeting: "It's so quiet, it's soooo quiet at the Lane haha #Afc forever #Wolves love ya."
Frimpong made his Premier League debut as a substitute against Newcastle in Arsenal's first game of the season.
