Lundell was born in Stockholm and started to play football with local club IF Ulvarna in the Swedish lower divisions.[4][1]
On 14 May 1955, Lundell made his senior debut for Hammarby IF in Allsvenskan, Sweden's top tier, scoring one goal in a 2–5 home loss against GAIS.[5][4]
He broke into the side as a regular starter in 1957, in a season where Hammarby got relegated to Division 2, and soon became known as a technically gifted playmaker in the midfield position.[5][6]
In 1957–58, Lundell helped the club to win a promotion back to Allsvenskan; the team scored an impressive 117 goals in 33 fixtures throughout the season.[7] He played a major part in establishing Hammarby in the top tier during the next four seasons.[8]
Lundell decided to retire from football due to injuries at the end of 1965, aged 31, playing his last game for Hammarby on 24 October in a 2–4 home loss against IFK Norrköping.[5] In total, he made 167 league appearances for the club, scoring 3 goals.[9]
He won 7 caps for his country in total, with the only competitive appearance coming on 21 June 1962 in a 2–0 away win against Norway in a European Nations' Cup qualifier.[11]
