[1][2] Spain B's first game is considered by some to be the one on 29 May 1927 at the Metropolitan Stadium in Madrid, where they beat the Portugal A team 2-0, thanks to second-half goals from Francisco Moraleda and Manuel Valderrama.

The team that started that day was Guillermo Eizaguirre, Miguel Garrobé, Emilio Perelló, Ramón Polo Pardo, Manuel Valderrama, Gonzalo, Domingo Carulla, Enrique Molina, Pedro Regueiro, Emili Sagi-Barba and Óscar, and the two substitutes that came after the break were Matías Aranzábal and Francisco Moraleda, with the latter scoring the opening goal.

[3][4][5] However, the Spain B team was only officially created 22 years later, in 1949, by the hands of the then national coach, Guillermo Eizaguirre, who had been the starting goalkeeper in the 1927 match.

[6] The next game was played only four years later, in 1953, this time thanks to Ricardo Zamora (the then Spain coach), to give the possibility to test under-21 or less experienced players, in addition to those involved with the senior national team.

Preparing the squad for the 1982 World Cup in Spain, the then Spanish coach, José Santamaría and the then Spanish U-21 coach, Luis Suárez, put together a block of 7 Friendly tests throughout 1980 and 1981, and in this block, Javier Urruticoechea established himself as a goalkeeper, playing 5 of the 7 games.
