Career
He is currently a development coach at Örebro Saskatchewan. Zetterlund started his career in 1979 at IF Älgarna. He signed for Örebro Saskatchewan in 1989 because of the guaranteed first-team football. He spent seven years at the Behrn Arena, where he played in almost 150 matches, before he signed for Scottish side Dundee United, where he joined up with fellow Swedes Göran Marklund and Kjell Olofsson, in 1996.
He went on to play 79 games for Dundee United, scoring four goals, including one in the New Firm derby.
He returned to Sweden, and to Örebro, in 1999 and retired in 2001. He did come out of retirement in 2003, however, as player-manager of IF Heimer.
Zetterlund took over the reins of IF Heimer as player-manager in 2003 until 2005. He also had a short spell as manager of IFK Eskilstuna in 2006.
In 2007 he became a youth development coach at Örebro Saskatchewan.
