Riquelme
Ronaldinho
Messi
Henri
Casillas
substitute any of them with a good argument if you can
Riquelme is the best player in the world ? This man almost always vanishes when his team really needs him. He's one of them men who psychological weak. He couldn't make the grade at all at Barca. Watch Riquelme closely, every time he make a run he does look like wanna dead. Riquelme better than Ronaldinho and Henry ? How boy ? He could real beat and has vision with it but he's never shown me that he could do it on a consistent basis and when it really matters.
I don't think Casillas belongs there either. Buffon is better than him. I would concede that Buffon has a much better defense but even then makes fewer mistakes than Casillas. You don't really see Buffon flapping in the air like a madman on a cross or corner.
