Article from the newspaper The Guardian :
Corruption and incompetence brought further complications for the Salvadoran players. The youngest squad in Spain, they were also the last to arrive for the finals, landing just three days before the clash with Hungary after a three day journey that included a stopover to play a friendly against a Brazilian club side. And the squad contained just 20 players rather than the permitted 22 because officials decided to bring along a couple of extra cronies instead. The players were outraged when they found out and tried to raise funds to bring their two jettisoned team-mates, Gilberto Quinteros and Miguel González, but, with all but one of them amateurs, they could not find enough money.

Despite his good performance in the preparatory phase for the World Cup, and although he traveled with the delegation to Spain, Mauricio Quintanilla was not among the players called up. He said later: “They preferred to take other players who had no more merit and I, who had only missed one playoff game, was taken for a walk in Spain. But I wanted to be in the field, to play ”.

Carlos Meléndez played some matches with national team before the competition, but was finally not called up. He won later the Salvadoran league title with Atlético Marte in 1985.
