The training camp will begin on Wednesday (March 10) - more than a week before the team's first game. 

Officials say support from the ESAOC and sponsors BocaDeli, Farmacias San Nicolas, SISA, Laboratorios Suizos and La Catalana has made the training camp possible.

ESAOC President Eduardo Palomo stated that the National Olympic Committee's contribution went towards accommodation, food and logistics costs associated with the camp in Guadalajara, which will also encompass a friendly versus Costa Rica.

"Joint efforts must be highlighted," said Diego Henriquez, sports director of the Salvadoran Football Federation.

"We thank the ESAOC for helping us to be in Guadalajara nine days before the debut."

El Salvador has only qualified for the men's football tournament at the Olympics once before, back at the Mexico City 1968 Games.

The team will be aiming to improve that record when the Confederation of North, Central America and Caribbean Association Football (CONCACAF) Olympic qualifying tournament plays out from March 18 to 30 in Mexico.

Two of the eight teams present will qualify for the Games.

El Salvador are in Group B with Canada, Honduras and Haiti, and face Canada in their opening game on March 19.

Hosts Mexico, the United States, Costa Rica and the Dominican Republic are in the other group.

Mexico and the US will be the favourites to advance to the Olympics from the CONCACAF region.

The other 14 places for the men's football contest at Tokyo 2020 have already been decided.
