Rio Ferdinand has narrated the time he slammed Ruud van Nistelrooy at Manchester United’s training centre over a harsh confrontation on a youthful Cristiano Ronaldo.

Ferdinand joined Van Nistelrooy at Manchester United in 2002, and they won the Premier League title together thereafter – with the center-back hailing his partner as a merciless finisher. In his words, “brutal finisher”.

In any case, the Dutch striker was proceeded onward by Sir Alex Ferguson when it turned out to be clear he was unable to play close by the arising Cristiano Ronaldo.

The former England centre-back Ferdinand said practice sessions could be tense, as there was “a ton of testosterone flying about”.

What’s more, he got in Van Nistelrooy’s face after the striker went in on Ronaldo’s Achilles.

“It was mad at United, things could just switch just like that [clicks fingers] in training,” Ferdinand clarified on his Vibe With FIVE YouTube show.

“I think all training grounds are the same, there’s a lot of testosterone flying about.”

Inquired as to whether he was at any point associated with a physical battle, Ferdinand said: “It never truly got to that.

“It’s funny, because I’ve got the biggest mouth on the training ground. I used to always be shouting and screaming and I used to love jokes.

“Obviously I got serious in training, with the games and that, especially on a Friday before the game on a Saturday, everyone’s playing, it would be hard games, fast games.

“One time something happened with Ruud. Ruud van Nistelrooy smashed Cristiano Ronaldo a couple of times, went down his Achilles.

“And then the ball went into Ruud and I smashed Ruud. I said, ‘What you doing? Why you kicking him for?’

“And then Ruud got up and he was [not happy] and all the players just got in the way, so nothing happened.

“But that’s the way it used to be in training. I was thinking, ‘Ronnie’s a young kid man, leave him alone, what you doing?’ but Ruud was an animal, an animal player.”

Van Nistelrooy scored 150 goals in 219 games for United, helping the Red Devils win an FA Cup and a League Cup just as the Premier League crown.

He proceeded onward to Real Madrid, where he won two La Liga titles.

Be that as it may, Ferdinand figures the previous PSV man, presently 44, would have crushed the Red Devils’ scoring records had he remained at Old Trafford.

He says his previous colleague was a conceived champ – to such an extent that he’d get surly in the event that he didn’t score, in any event, when United won.

“We’d play a game, we’d win 4-1, but he didn’t score, he’s in the training room after and he looked emotional.

“I thought, ‘Wow, this guy cares that we won this much, Ruud’s my guy’. I asked him if he was alright, he goes ‘I didn’t score! I didn’t score!’

“He was vexed! To put the nail in the coffin, Thierry [Henry] scored two on the same day so the Golden Boot was going away. He was fuming. He was so driven to score, he was born to just score.”
