After two seasons backing up Urruti, Arconada became the club's undisputed starter, being instrumental in back-to-back La Liga titles, which led – after the second – to a semifinal run in the European Cup.
He was seriously injured in 1985–86's league opener, which caused him to miss the remainder of the campaign and the 1986 FIFA World Cup. He still returned strong for three more seasons, helping Real Sociedad to two consecutive Copa del Rey finals before retiring at 35, with a total of 414 appearances for the club (551 overall); after that, he remained apart from the football world.
On 27 March 1977 Arconada played his first game for Spain, a 1–1 friendly with Hungary in Alicante, replacing Real Madrid's Miguel Ángel for the second half. Having captained the national side on many occasions he represented it at the 1978 and 1982 FIFA World Cups, as well as at UEFA Euro 1980 and 1984; in the latter competition his blunder resulted in the opening goal for hosts France, in the 0–2 final defeat: he appeared to have smothered a Michel Platini free-kick under his chest in a diving save, but he fumbled the ball, which slid off under his body and rolled slowly into the net.
Arconada's last game was a 0–3 defeat in Wales for the 1986 World Cup qualifiers. A severe injury while playing for Real ousted him from the final stages, being replaced by another legendary figure, also-Basque Andoni Zubizarreta.
During the ceremony following Spain's victory in Euro 2008, third-choice for the winners Andrés Palop wore Arconada's original Euro 84 final shirt, as he received the gold medal from Platini, now president of UEFA.

Arconada's younger brother, Gonzalo, never played professional football, but had an extensive coaching career, mainly in the third division. For a few months in early 2006, he coached Real Sociedad's first team.
