I am a barcelona fan so it may be bit difficult for me to be objective on the subject of Messi's rating. That being said I want categorically reject the assertion that the lad is overrated. At 18 years old he routinely humiliates defenders, shows good running off the ball and demonstrates an exemplary degree of confidence on the ball. His tactical vision is not refined yet. Often you'd see him make the wrong final pass but this will come with time. He deserved the rating he's given. To me he is more exciting than Rooney, Tevez, Adu, Robinho or any other young player. In the 1st leg against Chelsea, Messi was more dominant than Ronaldinho. How many 18 year olds do that ?
You want to talk about overrated players: Beckham (king) ,Crouch, Neville, Roberto Carlos (as a LB defensely) Ashely Cole, Raul (has suffered from an unprecedented dip in form since the arrival of Ronaldo), Miroslav Klose, Huth (Chelsea fans big up this man like he can't be beaten), Landon Donovan (Above average but certainly not World Class) Denilson(fan fan fan lose the ball, steups)
