Being european i have better opinion only for the players of my years who i have watched so i will refer to them.
Argentina:Gabriel Batistuta...A scoring machine,he drived Fiorentina to Champions League and in ths high positions of Campionato.
Bolivia:Marco Etchevery...after him,Bolivia became again a weak team and no way ready for a World Cup.
Brazil:Ronaldo...just world class.I could put Roberto Carlos in this place too,as he is the most stable defender in the last years.
Chile:Ivan Zamorano...Za-Sa over 20 goals in WC'98 Quals,what else?An real leader too.
Colombia:Oscar Cordoba or Carlos Valderama.
Ecuador:Alex Aguinaga...The brain of Ecuador NT for a decade.He played in a WC when he was already too old,so he didn't make sense.
Paraguay:Jose Luis Chilavert...The flag of this team...
Peru:Nolberto Solano...one of the first Peruvians that made sense in Europe.He refused his club to play for Peru too.
Uruguay:Alvaro Recoba...he didn't make much the NT till now but he is a techique player with a great flair,
Venezuela:Juan Arango...One of the very few good players that Venezuela has produced.
Continuing the thought of Tucidides Surinam could have an exceptional NT if Holland didn't steal players like Seedorf,Davids,Hasselbaink.
Panama: Julio Cesar Dely Valdes
Trinidad & Tobago: Dwight Yorke
Costa Rica: Hernan Medford
Mexico: Chuatemoch Blanco
USA: ?? no idea...i think they are all average players and same to my eyes.
Canada: Tomaz Radjinski
El Salvador: Raul Diaz Arce (he is the only serious Salvadoran i saw cause when their NT team played with Greece,their players weren't something important.
Honduras: Carlos Alberto Pavon
and some crap nations have their own legends...
Bermuda: Shawn Goater (a former bomber in Premier League)
Grenada: Jason Roberts (almost the same...)
