Edinburgh and Scotland scrum-half Greig Laidlaw conceded his side were "massively disappointed" after losing 38-6 to Munster.
The visitors to Thomond Park were well beaten in all facets of the game as they forgot to bring their defence, conceding six tries.
Edinburgh's shambolic discipline hardly helped their cause either as they were pinged 13 times by referee Wayne Barnes, with their European season coming to an end.
Alan Solomons' side had been in contention to possibly drop down into the Challenge Cup quarter-finals had they won, but they were thoroughly outclassed by an impressive Munster team.
"We are obviously massively disappointed," Laidlaw told the Scotsman.
"We felt we had a reasonable chance of going into the Amlin [quarter-finals], which would have been a good tournament for us, but we let ourselves down.
"We are disappointed with that, and with the manner of the defeat as well.
"We got off to a slow start - never a good idea away to Munster - but I felt in that middle period that we played well and started to claw our way into the game. We got a score on the board and some good field position.
"We got the yellow card before half-time, and then the try just after knocked the wind out of our sails. There was no recovery from there.
"I'm not going to take anything away from Munster. They played well and they won. But we are disappointed with our own performance today.
"We let ourselves down, we've let Alan [Solomons] and the boys down as well.
"It was just a poor performance and it's tough to take because we had been progressing as the season went on."
