As a dual Argentine-Spanish national, Messi was eligible to play for the national team of both countries. Selectors for Spain's Under-17 squad began pursuing him in 2003 after Barcelona's director of football, Carles Rexach, alerted the Royal Spanish Football Federation to their young player. Messi declined the offer, having aspired to represent "La Albiceleste" since childhood. To further prevent Spain from taking him, the Argentine Football Association organised two under-20 friendlies in June 2004, against Paraguay and Uruguay, with the purpose of finalising his status as an Argentina player in FIFA. Five days after his 17th birthday, on 29 June, he made his debut for his country against Paraguay, scoring once and providing two assists in their 8–0 victory. He was subsequently included in the squad for the South American Youth Championship, held in Colombia in February 2005. As he lacked the stamina of his teammates, the result of his former growth hormone deficiency, he was used as a substitute in six of the nine games. After being named man of the match against Venezuela, he scored the winning 2–1 goal in the crucial last match against Brazil, thereby securing their third-place qualification for the FIFA World Youth Championship.
