The new Maradona or the next big thing, there's always an incredible Argie around the corner according to some.
Try to recall a list and see how many there actually has been.
I'll start it off.

Andrés D'Alessandro. The new this the new that, the new Zidane etc etc etc etc etc. Never quite took off in the end and now is jumping from la liga club to la liga club not really making an impact anywhere. A decent player but no more use than a Patrick Berger or a Mendieta
