La Rochelle 24 Leinster 21
RONAN O'Gara joined Leo Cullen as the only man to capture the Champions Cup as a player and manager as his La Rochelle side defied their underdog status.
They needed a try from Arthur Retiere in the closing minutes to secure the French club's first major trophy as they broke Leinster hearts for the second successive season, having knocked them out in last year's semi-final.
Leo Cullen's side weren't at their blistering best, or weren't allowed to be, but still could have snatched a win at Stade Velodrome in Marseille until the dramatic finale.
Leinster didn't manage to cross over for a try, scoring seven penalties, due to poor La Rochelle discipline but ultimately that didn't prevent Munster legend Ronan O'Gara from getting his hands on the European Cup again.
