Originally, the squad was named with Ariel Ortega given shirt number 23 and Roberto Bonano number 24, as the Argentine Football Association had decided to retire the number 10 shirt in honour of Diego Maradona. FIFA, however, insisted that all squads were assigned with numbers ranging only from 1–23, prompting Argentina to amend their squad list.
The Saudi Arabian squad was the only one made up entirely of players from their country's domestic league and the only one with no players from European clubs. The Cameroon squad were made up entirely of players employed by overseas clubs, the Irish squad was made up entirely by players in the English league. Although Netherlands and Greece failed to qualify for the finals, their domestic leagues were represented by 18 and 10 players respectively. Altogether, there were 43 national leagues who had players in the tournament.
