The player in IF Elfsborg who holds most club and national records is Sven Jonasson. In 409 games, most appearances ever in Elfsborg, he scored a total of 252 goals in Allsvenskan, which makes it an all-time record. He played in Elfsborg throughout his career, which started in 1927 and ended 1947, a total of 20 years. The most remarkable achievement is his unbroken record of 344 consecutive games. A sequence that was broken when he missed his first game in 14 years because he failed to receive furlough during his military service. He was also the first goalscorer ever for the Sweden national football team in a World Cup. It was in the 1934 FIFA World Cup, where he scored two goals in Swedens 3–2 victory against Argentina.
