Leinster man-of-the match Isa Nacewa admitted his side had to do it the hard way after edging out Irish rivals Munster 18-9 to strengthen their position at the top of the RaboDirect PRO12 standings.
Ireland fly-half Jonathan Sexton kicked 12 points as Leinster won an uninspiring clash at Thomond Park in which Nacewa was one of the only men who threatened.
Munster’s points came from Ronan O’Gara while Fergus McFadden and Ian Madigan kicked a penalty and a drop goal respectively for the RaboDirect PRO12 leaders.
With both sides appearing to have one eye on next week’s Heineken Cup quarter-finals the game struggled to live up to its pre-match billing, but not in the physicality stakes according to Nacewa.
“We are exhausted after that: that is the hardest game we have had to play this season,” said Nacewa.
“This is always a tough place to come but we are happy to take the win after that.
“Coming off the defeat to the Ospreys it was a great win, but we still have a lot of things to work on this week. We’ll have to switch things up for next week but we are looking forward to it.”
