​​Manchester United legend ​Rio Ferdinand has revealed how ​Arsenal icon ​Thierry Henry made Ruud van Nistelrooy 'sad' in terms of individual accolades in the Premier League.

Van Nistelrooy had such a fierce rivalry with Henry that the Dutchman would get devastated if Henry scored for the Gunners.

The Dutch striker was obsessed over Henry's statistics and used to come in the changing room after a game unhappy if the Arsenal star had improved his goal scoring figures.

"You've had all these rivalries over the years, great players need great rivalries. They need rivalries. They should be looking at each other," Ferdinand reveals.

He continued, "Ruud van Nistelrooy used to come in changing room after a game, trust me, we're trying to win the league, we've beat someone 3-1 or 4-1, he's scored one goal, he'll come in and look up to the TV [shake his head] and go 'ohh'."

Rio further described the scenario in the dressing room with Nistelrooy as he concluded, "He sits down, [we ask] 'Ruud, are you alright, what's wrong?'. And he'll reply, 'nothing, nothing'. Then someone will go, 'Thierry has scored two today, Ruud has only scored one, so he's a goal behind now. And he's (sitting there devastated, and you can see it. I used to sit there, and this this guy is mad, we just won 3-1, he's scored a banger, set someone up as well, and he's disappointed."

Nistelrooy spent five seasons at Old Trafford and scored goals at an alarming rate, though he only beat Henry once to the Premier League Golden Boot in the 2002/03 season.

Henry, meanwhile, won an incredible four Premier League Golden Boot awards during his storied spell at Arsenal.
