Youth career

Jönsson, a farmer's daughter, grew up and began playing in her locality of Sövestad. She played for Sövestads IF, which was her first club, until she left to join Veberöds AIF before the 1993 season. Jönsson remained with Veberöds until signing for Malmö FF Dam prior to the 1996 season.

Malmö FF Dam and LdB FC Malmö

Jönsson began her Malmö FF Dam career in 1996. She continuously played there, even through the renaming of the squad to LdB FC Malmö in April 2007. She won an award for Sweden's Best Goalkeeper in 2003 and 2006 and was given the Football Figure award in 2003. Injuries slowed down Jönsson in 2007 and parts of 2008 when she tore her anterior cruciate ligament.

Jönsson left the team in 2008, when she seemingly announced her retirement from both club and international football.^[2]

Chicago Red Stars

Chicago Red Stars of Women's Professional Soccer in the United States selected Jönsson in the 4th round of the 2008 WPS International Draft on 24 September 2008, despite Jönsson's claims of retirement earlier upon her departure from LdB FC Malmö. It was announced on 3 February 2009 that she had signed with the American club, where she would be joined with fellow Sweden National Team member Frida Östberg from Umeå IK.^[3]

In the inaugural 2009 Women's Professional Soccer season, Jönsson played every minute of Chicago's campaign, allowing 25 goals in 20 games. Chicago failed to make the post-season tournament. On 28 September 2009, Chicago announced that they had exercised the team option for 2010 on Jönsson's contract. But in January 2010 she decided to join Umeå IK on a three-year contract, combining play with studies.

Umeå IK

Jönsson left Umeå and retired from football in June 2013, aged 35. She said her body was no longer able to withstand the rigours of top-level football.^[4]
