While Leinster were making their first appearance in the Heineken Cup final, Leicester were playing in their fifth, having won the competition twice, though not since 2002; they did, however, finish as runners-up in 2007.
However, after Stan Wright was sin-binned on the half-hour mark for an off-the-ball challenge on Sam Vesty, Leicester reduced the deficit to three points with another Dupuy penalty, before taking a 13–9 half-time lead via a converted try from Ben Woods.
Dupuy increased Leicester's lead to seven points with a third penalty goal just after the interval, but a converted try from Jamie Heaslip brought the teams level with half an hour left to play.
Then, with ten minutes left on the clock, Sexton squeezed a penalty inside the right-hand upright to win the match for Leinster.
Leicester, however, had reached the final on four other occasions: 1997, 2001, 2002 and 2007; they won the competition in 2001 and 2002, beating Stade Français and Munster, but lost out to Brive in 1997 and London Wasps in 2007.
Brown also missed with a long-range penalty, while an injured Nick Evans, who had come on as a blood replacement under dubious circumstances, sent a last-minute drop goal attempt wide to give Leinster a 6–5 win.
[9] As Heineken Cup holders and newly crowned champions of the Celtic League, Munster went into the game as favourites, but Leinster drew first blood with an early drop goal from fly-half Felipe Contepomi.
Based on their European Club Rugby ranking, Leicester Tigers were placed in Tier 1 for the pool stage draw, meaning that they would avoid being drawn with Toulouse, Stade Français and holders Munster.
[14] Leicester's 20–15 win secured them a place in the semi-finals, where they would play the Cardiff Blues,[8] who had beaten Toulouse 9–6 earlier that day.
Aside from two missed drop goal attempts from Johne Murphy and Aaron Mauger, extra time was largely uneventful and the match went to the first penalty shootout in Heineken Cup history.
Both teams successfully converted two more kicks before Martyn Williams wildly hooked his attempt wide and Jordan Crane slotted over to send Leicester into the final.
[18] John Gormley, leader of the Irish Green Party, said the team deserved "the country's fullest praise and admiration" for lifting themselves "to the very heights of the international game".
