Usually used for a bad, sloppy or useless soccer
player, particularly because of the stiff (like a tree trunk) movement of their body. Examples of troncos are
Diego Reyes, Maza Rodriguez , Kikin Fonseca and some even call Chicharito Hernandez a tronco because of his unorthodox ways of scoring goals. A tronco doesn't necessarily mean that the player is unsuccessful, Hernandez being the
perfect example.
Many call Kikin Fonseca the biggest tronco in Mexican soccer
history. Chicharito has
scored many goals in his career, but to many people, he's
still a tronco.
