The FA are probing a angry on-field confrontation between Arsenal and Liverpool players during Sunday’s pulsating clash.
Both sets of players clashed in the second half, just moments after referee Michael Oliver awarded the Gunners their decisive penalty, amid angry scenes on the field.
Oliver ran over to the touchline to speak to both Mikel Arteta and Jurgen Klopp after a row, during which angry words were clear exchanged between Arsenal and Liverpool players.
It is understood that Oliver made the managers aware of something one of the players was alleged to have said to an opponent.
