Leinster head coach Leo Cullen was relieved to get over the line following his side's second bonus-point win to go top of Pool 3 in the Champions Cup.
The 34-18 victory over Glasgow Warriors leaves Leinster sitting on 10 points in Pool 3, as Exeter prepare to travel to Montpellier tomorrow. Cian Healy crossed over for two tries, while Johnny Sexton scored 17 points in total, including a second half try.
Leinster's forward play was an important factor in their win, something which Cullen highlighted after the away fixture.
"It certainly wasn't easy," he said. "We prepped for difficult conditions and the two big moments were when Johnny backed the forwards to go for drives, one of them on the far side and one just before half-time.
"We started the second half well but Glasgow are a constant threat, particularly Stuart Hogg at 15 and Tommy Seymour on the right wing, while Finn Russell is a box of tricks as well. We needed to be on our toes all the time.
"Our forwards laid the platform for us and then we are more in control of the game and can play the game in the right areas of the field as a result of those tries."
Glasgow head coach Dave Rennie hinted they may be forced to prioritise the Guinness Pro14 after a second European loss. Warriors' defeat to Leinster follows a loss against Exeter in their opener last week.
Their European form is in stark contrast to their domestic form, where they have won all six of their opening PRO14 fixtures and have looked impressive in doing so. However after sliding to defeat against a clinical Leinster side, Rennie admitted he will be forced to consider prioritising the domestic fixtures, but not just yet.
"We will think about that in November or December," he said. "We will turn our focus back to Pro14.
"We're clearly not where we want to be and it's a tough pool as it is, so we will reassess things based on that and where our injuries are at and whether we end up prioritising PRO14 ahead of this comp, we'll decide that in December."
It was a familiar tale for Rennie, who saw his side dominated up front and wasteful with ball in hand at Scotstoun. Stuart Hogg marked his return from injury with a try and a bright performance.
Tommy Seymour added a consolation but Noel Reid's solo effort secured a bonus point for the visitors, with Rennie admitting his side had been second best throughout.
"It's a pretty solemn changing room as you'd imagine. We got outmuscled today and beaten by the better side, so we have to take it," he said.
