Roy Keane's reaction when Gareth Southgate bought up infamous stamp on live TV

Roy Keane was responsible for some awful challenges during his time as a professional footballer.

The Irishman’s worst challenge was undoubtedly on Alf-Inge Håland.

He also clashed with current England manager, Gareth Southgate, on the pitch.

On April 12, 1995, Crystal Palace and Man United met at Villa Park for their FA Cup semi-final clash.

The game was a feisty affair as tensions flared on more than one occasion.

In one moment, Southgate flew into a challenge on Keane and tried to take him out.

Keane stayed on his feet and reacted with a brutal stamp, sparking a mass brawl.

Keane and Southgate became colleagues after their playing careers came to an end as they both worked as pundits for ITV Sport.

In 2013, they both covered the FA Cup semi-final clash between Chelsea and Man City.

Sergio Aguero produced a brutal challenge on David Luiz that day.

And, when referencing the challenge after the game, Southgate felt the need to bring up Keane’s stamp on him nearly two decades prior.

He said: “That’s the worst tackle I’ve seen in a semi-final since Keane tried to castrate me at Villa Park around 15 years ago… although in fairness, that was retaliation as well!”

Southgate’s comments bought a smile to Keane’s face, who felt it was only right to apologise. View the moment below…

Happy Birthday to @England boss Gareth Southgate
