Speaking after the game yesteday, Liverpool manager Brendan Rodgers and managing director Ian Ayre hinted that the club would take action against Suarez.
Ayre, who cancelled a trip to Australia in order to personally deal with the matter, said the incident did not "befit" the behaviour of a Liverpool player.
"Luis is aware that he has let himself and everyone associated with the club down," Ayre told the club's official website.
"We will deal with the matter internally and await any action from the Football Association."
The Football Association are yet to announce their own course of action, but Suarez will likely face a lengthy ban.
