The 2006-07 campaign delivered a glorious domestic double for Celtic, with The Bhoys clinching the Scottish Premier League title by 12 points and winning the Scottish Cup. Under the charge of Gordon Strachan, the league title was dramatically secured by Shunsuke Nakamura's spectacular, injury-time free-kick against Kilmarnock. Spearheading the league attack was the powerful forward Jan Vennegoor of Hesselink, whose 13 goals proved vital. The season was also immortalized by a historic run to the UEFA Champions League Round of 16 for the first time, where they took eventual winners AC Milan to extra time. It was a triumphant year that cemented the club's domestic dominance and remains a defining chapter in the legacy of The Bhoys.
