Latas ... given his skill and abilities he should have been playing for Real Madrid or Barcelona not Porto or Rangers.
As much as I get what you saying, I would never rate Latapy the a "biggest" underachiever. I don't really agree that there's any basis to say he had the skill to play for a Real Madrid or Barca anyway.
Anyway, I pick Wise #3, Dwarika #2 and Jemmot #1
Given what I heard about Lester Peltier, I would put him in this poll too.
We should start a thread for biggest overachiever.
