In 2008, he featured in a 10-man shortlist for Iceland's greatest footballer of all time.
Jónsson started his career at his hometown club IA Akranes before moving to English club Sheffield Wednesday in February 1985. He spent four years at Wednesday, including a brief spell on loan to Barnsley in 1986, playing 67 times for them. He made his English league debut against Leicester City in March 1985. He was signed by Arsenal in July 1989 for a fee of £475,000 and made his Arsenal debut at home against Manchester City on 14 October 1989. However his period at Arsenal was wrecked by injury and he made just nine appearances in three seasons for the London side, scoring once in the league against QPR in November 1989. He was part of the Arsenal side that won the old First Division in 1991 but only played in two matches which was not enough games to earn a winner's medal.
Jónsson rejoined IA Akranes in the summer of 1992 and spent another three seasons there, before joining Swedish side Örebro SK in 1995. Two years later he joined Scottish side Dundee United, where again injury reduced his opportunities to play; he made 43 league appearances, scoring once against Motherwell. He left United and signed for IA Akranes for a third time, before finally retiring in 2001.
Additionally, during his career Sigurður represented Iceland at international level 65 times, scoring three goals. He made his international debut in a Euro 84 qualifier against Malta on 5 June 1983, aged just 16 years and 251 days. He came on at half time in a 1–0 win. This made him the youngest player to have appeared in a European Championship qualifier, a record he held until it was taken by Martin Ødegaard of Norway in 2014. He played his last game for the national team on 9 September 1999 against Ukraine.
