(The Mortar of Rufino): 187 goals in 185 games for river, in the 30's.
The best Argentine team ever: La Maquina

Angel Labruna, the greatest scorer of Argentine football along with the Paraguayan Erico.
La saeta rubia (the blonde arrow), one of the best players ever to play the game: Alfredo Di Stefano
. He also played for Real Madrid, I'm not sure if he did well though...
One of the best Goalkeepers ever: Amadeo Carrizo
Enrique Omar Sivori
, one of the best argentine forwards, played for River in the 50's. With the money of the sell to Juventus of Italy, River finished its new stadium. I think he did well in Italy...

. The best Argentine defender ever, along with the next player...
El Gran Capitan (the great captain) Daniel Passarella
As Carrizo, one of the best goalkeepers: El pato (the duck) Ubaldo Matildo Fillol
