Alexis Mac Allister was involved in a disagreement with Cristian Romero on Instagram following Tottenham's controversial victory over Liverpool.
Tottenham won 2-1, with Joel Matip scoring a late own goal, while Liverpool ended the game with nine men following the dismissals of Curtis Jones and Diogo Jota.
Liverpool received an apology from PGMOL after the game, who admitted that Luis Diaz's goal was wrongly ruled out for offside.
A statement from PGMOL admitted that a 'significant human error' had occurred when making the decision.
