Ronaldo comes in second here, which seems to be his tendency this year.
Ultimately he may be remembered as the greatest player to ever play at United.
He was joyously naive when he arrived in Manchester, and so were we. It took at least three years before he became pompous and whiny, and those three years will always belong to United fans who saw him in his purest, rawest form.
Whether or not he continues to evolve dictates where his best years will have been ultimately spent.
But, despite only being in Manchester for five years, he makes the grade above Giggs for many reasons.
Firstly, Ronaldo filled an immediate gap on the pitch and off it, arriving the summer Beckham left. In Ronaldo, United had another good-looking, flare player who appealed to casual and hardcore fans alike. In fact, they had, successively, the two most marketable players of the decade in the two number sevens.
Just a few of Ronaldo's most memorable goals for United, besides innumerable free-kicks, consist of a triple step-over juke-burger served rare to Ricardo Gardner against Bolton in 2006, a towering header against Chelsea in the Champions League final of 2008, and his last strike for United, a 40-yard howitzer against Porto, sending his team through to the final again in 2009.
Despite scoring 42 goals in 2007-2008, claiming the Ballon d'Or and FIFA WPOTY honors, among hardcore fans, Ronaldo's best year in red was actually the preceding year, 2006-2007.
He is the fastest player in the world with the ball, according to a recent study.
He was the best player for United for several years, including through two of his three EPL championship campaigns and United's European triumph (United's best player in 2008-2009 was Vidic).
However, in his last year with United, he was off-form consistently, always whining at teammates, blaming referees, and generally being a huge plonker. We know, in hindsight, that he had already agreed to a Madrid move by then.
Now, as we enter 2010, he may not be considered the absolute best in the world, he is still the most dominant. His aerial presence, emotional leadership, willingness to attempt and convert penalties, dribbling, ambidexterity, and dead-ball striking abilities make him the most complete player in the world still, if not the most technical.
