Willum led Þróttur to Iceland's top league, the Úrvalsdeild in 1997. The wait had been long as Þróttur last played at the top level in 1985. In 2000 he became the manager of Haukar, and in 2002, he was appointed manager of KR and led them to two successive championships in 2002 and 2003. In 2004 KR finished without a title and Þórsson's contract was not renewed. He took charge of Valur who had just been promoted to the Úrvalsdeild and finished the 2005 season in 2nd place after champions FH.
Valur won the 2005 VISA-bikar with a 1-0 victory over Fram. In 2006, Valur ended the season in 3rd place and in 2007 Willum managed Valur to their first League title in 20 years and won Manager of the Season in Landsbankadeildin. He left with mutual agreement on 1 July 2009. On 29 September 2009, after the season had finished for the year, he was appointed the new manager of Keflavík.
