With reigning European champions Saracens and French giants Racing 92 also in their pool, Van Graan appreciates the importance of getting their European campaign off to a winning start.
"That last try could be vital," said Van Graan.
"It doesn't matter when you score as long as you get four. The last two years we started the Champions Cup with draws away from home so we were happy to get the win.
"A lot of people didn't give them a chance but I knew all week it would be tough and I have a lot of respect for Allen Clarke.
"But we gave away too many high shots and we will have to improve our discipline next week. We exploited some areas of space which was pleasing and we created some nice set play.
"Most games in the world of rugby are won in the second half. It was a titanic battle and we are grateful to have won."
Tries from Jeremy Loughman, Keith Earls, Andrew Conway and James Cronin, along with 12 points from the boot of Tyler Bleyendaal, were enough to get Munster over the line.
