Leinster booked a semi final spot in the Heineken Cup with a gritty 6-5 victory over Harlequins at the Twickenham Stoop on Sunday afternoon…

The visitors prevailed thanks to a heroic defence, and two first half penalties by Felipe Contepomi.

Full-back Mike Brown’s try with 14 minutes left finally breached the Leinster defence, only for replacement Chris Malone to miss the conversion.

Speaking after the game, Leinster Coach Michael Cheika said: "That was a tense game. We made too many unforced errors in the first half but we showed a lot of character and I’m delighted for the team and for the supporters who were fantastic today.

"We know that we will have to bring our performances up another level for Munster. Whenever you play them you always get a very tough game. I was pleased with how we coped with the physical and mential pressure."
