David Beckham became something of a trend setter during his time in the Premier League with Manchester United.

Whether it was dying his hair blonde, growing a mohawk or donning the latest Adidas Predator football boots, whatever the Englishman did seemed to catch on with youngsters.

It could even be argued that Beckham started the trend of professional footballers getting tattoos all over their bodies.

Beckham first went under the needle in 1999 following the birth of his eldest son, Brooklyn, before getting further tattoos on his upper back and forearms in the early noughties.

For the most part they were hidden, though, so the main reason Beckham became a style icon was for his hair.

In his early days as United's poster boy he had curtains before going bald, having a mohawk, growing his hair out, having braids and later going bleach blonde.

Nowadays Beckham is sporting short back and sides with spiky hair, but there was once a time when his haircut was too extreme in the eyes of Sir Alex Ferguson.

Back in 2000, the former England captain had grown a mohawk ahead of the Charity Shield against Chelsea but was hiding it from Fergie, knowing he wouldn't approve.

So when Beckham unveiled his new style in the dressing room before the game at Wembley, Sir Alex wasted no time in telling him to shave it off immediately.

Take it away, David.

"I walked in the changing room and he hadn't seen it because I was too scared to even show him," Beckham said to Otro, per the Daily Mail.

"I'd gone into training the day before with a beanie on, trained in a beanie, gone back, walked in the hotel, had a beanie on, had dinner, beanie on, breakfast beanie on, bus on way to stadium - beanie.

"Then as I got ready for the game I took it off. He said: 'Go and shave it off.'

"I giggled and he was like: 'No, I'm serious. Go and shave it off.' So I had to find a pair of clippers and I shaved it off in Wembley Stadium. [The] manager always rules.

"It's a lot more normal to do it these days, it's a lot more normal to have a mohawk or a tattoo on your neck or wear coloured boots.

"When we were growing up the manager wouldn't let us even step on a pitch wearing a pair of red boots or a pair of white boots. Simple as that. Things like that have definitely changed."

Classic Fergie. Beckham knew he had taken a risk by growing a mohawk and sure enough, his legendary manager wasn't impressed.
