After several seasons in the lower divisions Arnefjord got his breakthrough after he was bought from
FC Väsby United to
AIK when AIK returned to
Allsvenskan in 2006. A bitter moment in the 2006-season was a misunderstanding between Arnefjord and AIK's goalkeeper
Daniel Örlund, which led to Arnefjord heading the ball into his one goal in the home-match against
Helsingborgs IF. When the league finished two weeks later, AIK was only one point behind the league-winners
IF Elfsborg, had Arnefjord let the goalkeeper make the save, AIK would have won the title. Arnefjord moved to
Norway to play for
Aalesunds FK, where he captained the
Tippeligaen side until the end of the 2014 season. Arnefjord helped Aalesunds win its first two
Norwegian Football Cup finals (in 2009 and 2011) during his spell with the club. == Career statistics ==
