Answer
The Eredivisie, the Netherlands' premier football league, saw AZ and FC Twente claim the championship titles in 1981 and 2009, respectively. In 1981, AZ secured their first and only Eredivisie title to date under coach Georg Kessler. Twenty-eight years later, in the 2008-09 season, FC Twente, led by manager Steve McClaren, clinched their first and only Eredivisie title in club history, surpassing traditional powerhouses Ajax, Feyenoord, and PSV Eindhoven.
