Career
Vergoossen began his managerial career in 1978 with VVV-Venlo, managing the club for 12 years until 1989, after which he managed MVV for nine years and Roda JC for three years. In 2006, Vergoosen moved to Japan and managed Nagoya Grampus Eight, which had previously been successfully managed by current Arsenal manager Arsène Wenger. In 2008, Vergoossen was appointed interim manager of PSV Eindhoven in January 2008, whom he led to winning the 2007-2008 Eredivisie title.
After his successful tenure at PSV ended, Vergoossen moved on to work for his previous club Genk as an advisor on a part-time basis.
In January 2009, after his successor Huub Stevens resigned at PSV, Vergoosen was named as one of the top candidates for the managerial role, having successfully led the side to the Eredivisie title the previous season. 1978–1989 – VVV-Venlo
