Roy Keane is perhaps the scariest pundit in English football.
The Irishman is known for his short temper and isn't afraid to start arguments with his fellow pundits on Sky Sports.
Many have tried to challenge him, including Graeme Souness and Gary Neville, but it's always the former Man United captain who comes out on top.
It takes a very brave man to bite back at him but that's exactly what Micah Richards did on Sunday afternoon.
The two were joined by presenter Dave Jones and fellow pundits Neville and Jamie Redknapp for Super Sunday.
Richards was speaking about how he burst on to the scenes as a youngster but failed to live up to expectations.
That's when Keane cut in. The Irishman questioned Richards for claiming he 'burst onto the scene'.
And then Richards snapped. Many pundits would perhaps laugh it off but the former Man City defender did not let it go.
"Do you not remember my header against [Aston] Villa?" He responded. "Do you not remember that, no?"
Keane interrupted once again by saying 'not many defenders burst onto the scene'.
But Richards would not let it go.
"Well, hold on! I played for England at 18 [and was] the youngest ever defender to play for England. I would say that's bursting onto the scene."
Jones, Redknapp and Neville weer left in stitches watching the two go at it.
Fair play to Richards. Keane decided to challenge him but the former England defender stood up for himself when not many would.
Many who are brave enough to stand up to Keane don't usually win.
But the Irishman sat there in silence after Richards was done. Maybe he was just stunned that Richards would dare chat back to him.
The five pundits joked about the incident during the ad break. Watch it below:
That episode didn't stop Keane being at his brutal best, mind.
Just before Chelsea and Everton's players were about to walk out, he claimed that his daughter was stronger than Adam Lallana.
