Liverpool manager Jurgen Klopp remonstrated with a fan who ran on to the Anfield pitch and collided with his players as they celebrated the final goal in Sunday's 7-0 thrashing of rivals Manchester United.
The supporter went to celebrate with Liverpool players and appeared to slip - colliding with Andrew Robertson and Curtis Jones, who both looked to be in some discomfort.
As the fan was escorted off by stewards, Klopp was seen shouting at the fan.
The incident was discussed on BBC's Match of the Day 2, with Birmingham City captain Troy Deeney, speaking as a pundit, saying: "It it is something we spoke about at the back end of last season with fans coming on the pitch, and then we had the Aaron Ramsdale incident.
