Matt O’Connor admitted that it took time for Leinster to find their feet against Munster.
The Blues edged the top of the table RaboDirect PRO12 encounter 22-18 at the Aviva but had to come back from a 12-3 deficit in order to so so.
Ian Madigan scored two penalties before the break to get Leinster on the board and O’Connor said that that period was crucial to the win.
“That ten minutes was huge,” O’Connor told RTÉ Sport:
“We spoke about it a lot during the week. At certain stages in the game that they would be very hard to break down and we probably didn’t execute enough and well enough in the first 25-30 minutes of the game and they got entry into the game and at that point they were very, very good.
“We had to work incredibly hard; they defended very, very well in the first half.
"They got some reward at scrum time and at 9-0 it’s looking like a pretty average evening.
"But the boys clawed their way back into it and the second-half performance was fantastic.
“But thankfully we got the rub of the green, we kicked a couple of penalties and we were pretty happy at half-time with where we had been relative to the score early and I thought the second half was a good performance."
