Aronsson joined Linköpings in 2002, when they were called BK Kenty, and remained with the team for six seasons, making 121 appearances.
Linköpings' management told her that she had finished developing and that their other forwards (Josefine Öqvist, Kosovare Asllani and Jessica Landström) were better equipped to lead the team's trophy quest.
After nine goals in 34 games across two seasons, Aronsson declined the contract extension and moved back to live in Linköping.
She scored her first – and only – goal for the national team in a 1–1 friendly draw with England on 9 February 2006 in the Cypriot town of Achna.
[6] In August 2008 Aronsson replaced the injured Josefine Öqvist in the Sweden squad for the 2008 Beijing Olympics.
