**Exactly ten years ago to the day, Ospreys made history – beating Leinster in the inaugural Magners League Grand Final and becoming the first side to win the league title for a third time.** Since its inception in 2001, the Celtic League had been contested in a straight league format but changes were afoot ahead of the 2009-10 campaign. Following an 18-game league season, the top four teams would move into the semi-finals with the winners of those matches going head to head in the Grand Final – creating a showpiece contest that has delivered countless iconic moments over the past decade. For the ten-year anniversary, we have taken a look back at that first Final as Welsh and Irish rugby royalty went head to head in Dublin, with history on the line.
