Clermont Auvergne 15 Leinster 19
A superb second half display saw Leinster book their place in the Heineken Cup final with a 19-15 triumph over Clermont Auvergne.
Although both sides looked to spread the ball wide and attack from deep, four Brock James penalties to Jonathan Sexton's two was all either team had to show from their first half excursions.
However, the Irish province controlled the second period with a converted Cian Healy touchdown, a Rob Kearney drop-goal and a Sexton three-pointer which secured the victory.
James' fifth penalty was Clermont's only points of the half, although Wesley Fofana was denied a try in the dramatic final moments.
Despite their position as defending champions and convincingly dispatching the Cardiff Blues 34-3 in the previous round, the visitors knew they were in for a stern examination of their abilities.
With a backline containing the strike power of Lee Byrne, Sitiveni Sivivatu and Fofana, Clermont were given the tag as favourites by some quarters.
But it was the Irish province that controlled the opening 15 minutes. Sexton and Isa Nacewa were particularly prominent as they made several inroads into the hosts' territory.
Leinster's stand-off then rewarded their dominance with a penalty, but the French side struck back when James kicked one of his own.
When these teams last met in the knockout stages, the home side's fly-half suffered from the yips which ultimately caused their downfall.
This time, though, the out-half was calm and composed, and took his side into the lead with a second penalty.
Sexton levelled matters with another three-pointer, but James was seeing this match as a chance of redemption as he kicked Clermont into a 12-6 half-time lead with successive penalties.
However, a minute into the second period Leinster showed why they are European champions. An inside ball allowed Kearney to gallop through a gaping hole before the full-back fed Healy to go over.
Sexton converted before Kearney added a rare drop-goal from just inside the hosts' half as they opened up a 16-12 advantage.
Clermont's stand-off reduced the arrears with a fifth from the tee, but his opposite number restored that four-point lead.
But in the penultimate minute, Fofana crossed the whitewash only to be denied by the television match official who adjudged that he knocked on.
