1. Cristiano Ronaldo

He may be the best player we have ever seen in the world.  He may be the best player we have ever seen in the Premier League.  Cristiano Ronaldo was once a Manchester United golden boy. When Ronaldo scored a big goal against Manchester United at the tender age of 18, Ferguson and the United players fell in love.  12.24 million dollars for one of the worlds best players looks like a bargain.  Ronaldo would go on to score 84 times in 96 appearances, while also adding a Champions League, a Ballon d’Or, and three Premier League titles.  Ronaldo will likely go down as the best Manchester United player ever.
