After watching a stunning second-half display from his side yesterday, Leinster head coach Joe Schmidt declared he wants more from his players.
"I'm delighted to get the result we did and delighted with some of the play that we managed to construct and finish to get the six tries," Schmidt said.
"At the same time, we know it wasn't a perfect performance and Saracens probably lost a little bit of interest toward the middle part of the second half. I wouldn't say they offered up soft tries but some of the tries came relatively easily.
"I guess the reality is next week is a whole different ball game again. It's a six day turnaround and there are a number of things we still need to work on.
"I thought we got off to a fantastic start. The first two tries we scored were superb. Conditions were very tough out there and to get the 12 points up was fantastic but then to allow them back into the game so easily into the gale, was very, very frustrating.
"A crucial thing for us was to score just before half-time. There was some really good concentration and co-ordination that went into that and that allowed us to go into half-time with the buffer we needed to give us the confidence to take another step."
With qualification achieved, Schmidt's focus now turns to getting a win in Paris next week against Racing Metro to secure a home quarter-final.
"We know we have to win in Paris to get a quarter-final back home. We will certainly endeavour to do that. We have put ourselves into a position now, that we would be crazy not to [go for a win in Paris]."
