The Irish Times', John O’Sullivan reflects on a fraught night for Leinster which tested the nerves of the home fans.
"It wasn't a night for the faint-hearted, an understatement that the Leinster supporters only fully appreciated on the final whistle. Victory was measured in millimetres. The European champions survived but it was a massively uncomfortable experience for their supporters and one suspects, for the management team.
"Ecstatic scenes at the final whistle were as much about relief and, while victory will largely eradicate the palpitations of the previous 80 plus minutes, it shouldn’t camouflage a night when, had Clermont a place-kicker, they would have managed a famous win.
"That’s not to denigrate the courage and at times breathtaking quality of the Leinster performance but they made it so hard for themselves. Ill-discipline, a creaking scrum in the second half and the concession of two soft tries almost cost them."
