The 2005-06 campaign delivered a triumphant return to glory for Anderlecht as the Purple and White clinched the Belgian First Division title on the dramatic final day of the season. Under the guidance of manager Frank Vercauteren, the team's attack was spearheaded by the clinical centre-forward Mbo Mpenza, whose 11 goals were vital, ably assisted by the mastery of veteran Pär Zetterberg and the emergence of teenage prodigy Vincent Kompany. This hard-won success secured their 28th domestic championship and remains a defining chapter in the club's modern history, contrasting with a tough campaign in the UEFA Champions League.
