The game at a glance
Man of the match
Indubitably, Heaslip. The wonder is that some of us feared in March that the No 8 simply could not maintain his searing international form. If anything, he has surpassed his own standards. "It's like having Rocky back," enthused Shane Jennings.
Leinster's fourth successive win was a particularly sweet victory for Michael Cheika, who admitted that he failed to understand the peculiar niceties of the internecine inter-provincial rivalry when he first arrived five years ago.
When Leinster shook the sleep from their eyes in the second half, a stunningly constructed try finished by Rob Kearney secured them the match foothold, even if via merely a four-point lead, their stern defence would never relinquish.
Munster are either in chaotic freefall or tortuous rebuilding. To reach two semi-finals this season represents either stunning over-achievement or a singular illustration of an institution in decline. Within the camp, the introspection will be painful; without, the examination will be searing.
Michael Cheika seems set fair to deliver a third trophy in three seasons as he sets sail for new pastures, his lasting bequest a cultural legacy of achievement and high standards.
Tony McGahan is under severe pressure as he surveys a coaching set-up which is being severely questioned and a squad with a disproportionate amount of players past their best.
Nigel Owens' presence for the Toulouse defeat allowed Leinster to absorb some of the painful lessons from that semi-final; albeit dominant in the scrums, their tight-head bored across as freely as the French did.
A rocking RDS may prove to be the difference between the winning and losing of the final. Three times as many pitched up in Dublin compared to Swansea 24 hours earlier.
