Rio Ferdinand has opened up on a moment of madness he had, after a football game between Manchester United and rivals, Manchester City.

According to the former defender, the incident took place on the day of the FA Cup semi-final between United and City back in 2011.

Our noisy neighbours won the game eventually, no thanks to a goal from Yaya Toure, and with tensions high, tempers were expected to fly around.

Ferdinand said that after the game, instead of leaving the stadium, Mario Balotelli went and gestured at United fans, and that passed him off so much that he had to be held back by teammates.

“That semi-final, that was the moment when I thought ‘OK they (City) are here to stay,'” he said on his YouTube Channel, while chatting with ex-City man, Vincent Kompany.

“That was when Balotelli, remember what happened after the game? I wanted to kill him that day.

“I get on with him but at that moment in time…he was celebrating and giving gestures to our fans.

“And I was like that is disrespectful and I was going nuts.

“He was a mad talent, what happened with his career?”

United and City’s rivalry became stronger from the 2010s, after the owners of Manchester City pumped so much money into transfers, to acquire some of the best players in the game.
