Making his debut at 17 years of age in 1958, Eriksen played a total of 142 top-tier games for Vålerenga in which he scored 58 goals. This makes him Vålerenga's second-leading scorer all-time in the
Norwegian Premier League behind
Morten Berre who scored 62 goals. In
1963, Eriksen scored 16 goals to become top scorer in the Norwegian top division. In
1965, he was a member of the Vålerenga side that became league champions for the first time in club history. In the championship-deciding game against
Steinkjer, Eriksen fractured his foot, but was somehow able to finish the match (substitutions were at that time not allowed after the start of the second half). ==International career==
