Personally I think he is underrated. He gets plenty of praise but I think the celebrity aspect of him has tarnished the opinion of him as a footballer.
For one, I haven't witnessed many players like him to can cross the ball the way he could. He was a player who needed to feel loved. At the time I was gutted when he had the falling out with Fergie. As I got older I began to realise that sometimes being ruthless and tough is sometimes required. I think Ferguson felt he had lost control of Becks and maybe he had to sell him to maintain complete control of his dressing room.
I will always have a soft spot for Becks. The first time I watched United was actually at Villa Park. Went over with my dear granddad (Villa fan) and a friend of his who had tickets in the away section. My grandad and uncles were in the Villa stands (That side of family are all Villa). It was the only time I was ever in the away section. United won 1-0 and Beckham scored. I remember when I was going over that I wanted to see loads of goals. I would have been 10 years old. We scored 1 goal and I will never forget that feeling. I will never forget chanting ''There's Only One David Beckham''. I was a fan of United for a few years, my Dad was always United so naturally I am too. I couldn't wait to go again and the following season I got to finally attend Old Trafford. Sadly, Beckham was sold and as a kid I was heartbroken! I remember coming home from school, turning on the TV and it was all that was being reported on the news channels.
My grandad passed away a few years back and I have lovely memories of going to the football with him and I always think of Becks scoring that goal when I think of going to games with my grandad. This was the game -

Becks' passing was also top notch. The way he could pass the ball 35 - 40 yards and made it look easy. His free kicks - I think he is one of the best free kick takers of all time. His performance against Greece. The game where he wanted to redeem himself for the sending off a few years prior. That game, he made sure his country was qualifying for the world cup and to score a late free kick under extreme pressure, to me, defines greatness. He covered every blade of grass that day. Tackles, covering, passing, the free kick. My oh my. As a young Irish lad watching it, I was delighted that Becks won!
Apologies for the long post! Beckham was just so important to my childhood and my love of football and more importantly, my love for United.
