VINA DEL MAR, Chile -- What's past is prologue. You don't need to brush up on The Tempest to know that and Friday's Copa America quarterfinal clash between Argentina and Colombia is chock-full not just of prologue, but symmetry too.
It was 10 years and three days ago that these two teams met in the Round of 16 of the Under-20 World Cup in Holland. What's remarkable is how many of those players became full internationals and today form the spine of the Cafeteros and Albiceleste.
The Argentine newspaper "La Nacion" looked them up. Lionel Messi, Sergio Aguero, Lucas Biglia, Pablo Zabaleta, Ezequiel Garay and Fernando Gago were all there and they'll be in Vina del Mar.
