Leinster 29 - 28 Clermont Auvergne: Surefooted Sexton sends Leinster into Heineken semis

Sexton delivered the knockout blow in the 73rd minute as an epic contest served up a heart-stopping final quarter.

Clermont fly-half Brock James missed two glorious chances to set up a semi-final against Toulouse or Stade Francais, who meet tomorrow, when he fluffed a pair of drop goals in front of the posts.

The second failed attempt was the last kick of the game and it concluded a tortuous evening for the hapless Australian, who was off target with five of his nine shots at goal. In contrast Sexton was almost immaculate with the boot, kicking seven from eight to finish with a 19-point haul.

Jamie Heaslip's barnstorming pair of first-half tries were almost forgotten amid the tightest of finishes, but the Ireland No8 was the star of a muscular Leinster back row. However, in try- scoring terms he was overshadowed by Clermont winger Julien Malzieu who ran in a hat-trick.

Clermont dominated the opening exchanges and powered ahead in the 12th minute through Malzieu. A chip ahead from James did the initial damage, with Gonzalo Canale gathering before finding Aurelien Rougerie marauding off his wing and he sent Malzieu over for an easy finish. The conversion was landed by James, who quickly added a penalty.

Leinster hauled themselves level with a Sexton penalty in the 19th minute. Better was to come in the 23rd when a piece of magic from Brian O'Driscoll saw the Ireland captain draw Marius Joubert before deceiving Rougerie with a crafty offload to Heaslip. Heaslip had support but opted to go it alone by stepping inside back row Julien Bonnaire and crashing over with Sexton converting. Heaslip crashed over for his second try in the 34th minute. The Ireland No8 won possession at the lineout and then picked up after a drive from fellow back row Kevin McLaughlin to barge over under the posts. Sexton converted and then added a penalty to put Leinster 20-10 ahead going into the break, with Morgan Parra squandering a chance to reduce the deficit.

Malzieu skinned Shane Horgan to add his second try three minutes into the second half as Clermont clinically worked an overlap created by tieing up Leinster's pack. James missed the conversion but slotted a penalty.

Shane Jennings and McLaughlin accumulated hard yards to set up a good field position finished by three points from Sexton. The tension grew with James finally hitting the target and then Clermont surged ahead, capitalising on two errors from Horgan to send Malzieu over for his third.

James hit the conversion but Clermont's hearts were in their mouths as tournament match official Geoff Warren poured over replays of Eoin Reddan attempting to ground the ball over the whitewash, eventually opting against awarding the score. Sexton kicked another penalty and Leinster's prospects improved as James missed an easy drop goal after Clermont had done all the hard work and Sexton fired his fifth penalty before James' wasteful late attempt.
