I want to make a distinction here
There are superstars like George Best, who never got a chance to play in the world cup.
Then there are superstars like Cryuff, Platini and Usebio, who played in the world cup, shined in it, but failed to win.
then there are superstars like Messi and Waryne Rooni who played in the world cup and did not meet expectations.
I think it's fair to ding the the third group, and use their failure to shine in the world cup to bring down their over rating a notch.
