Leinster may have swatted Wasps aside in their Champions Cup pool opener, but the sky-high standards of the reigning European and Pro14 champions means that the flaws from Friday night's stunning win have been critically analysed.

They led 14-3 at half-time in the RDS and cut loose on the turnaround, producing some sparkling rugby under the lights to gallop to an eight-try 52-3 success.

The imagination and fluidity of their attacking play was breathtaking, but scrum coach John Fogarty revealed that one area of their game stuck in the craw.

"I think we were quite slow with our lineout process," he told RTÉ Sport's Gary Moran.

"We were slow to even get to the lineout, and when we were in there we were a bit clunky in our movement. It really is down to individual error. You'd never throw someone under the bus.

"I just think we weren't as fluid in our movements when we were in the lineout and we were slow in our decision making getting into the lineout. Those two areas rattled us a little bit and that led to errors. It led to us missing lineouts.

"It's frustrating for some of the players. For us as a unit it's something we'll have to really look at because when we go to Toulouse, that's an area they were strong on against Bath and it will be an area they'll look to get after us."

The trip to France on Sunday will ask more questions of this Leinster side but they look incredibly well equipped to defend both their titles this season.

Toulouse are sixth in the Top 14 and plundered victory at Bath in their pool opener, albeit with a helping hand from Freddie Burns whose disastrous error of judgement cost his side dear.

Fogarty says the aim for Leinster is simple: to hit the standards they set each day across a full 80-minute performance.

"It's going to be an exciting day," he added. "There'll be a super atmosphere, it'll be very hotly contested. Hopefully we can stay on point and perform. 

"We're realistic about the challenges that lie ahead of us.

"It's really important that you're sticking to your processes, you're staying focused. Every point counts in this competition. For us as a team, as a group of players, as a squad, as a place, to put a performance out there for 80 minutes is important to us.

"We have to prepare again. We have to do the whole thing again, make sure our mindset is good, get to Sunday in a good space and hopefully perform. That's the challenge now."
