Gloucester boss Bryan Redpath failed to hide his disappointment after his side succumbed to a comprehensive defeat at Glasgow on Friday night.
Redpath's men were beaten 33-11 by the Magners League leaders to leave their hopes of Heineken Cup qualification hanging by a thread.
And although the result and its consequences were hugely disappointing for the former European Challenge Cup winner, it was the manner of the performance that frustrated Redpath the most.
"From minute one, we didn't turn up," admitted Redpath.
"Physically, we fell off two or three tackles. Our execution just looked flat. I don't know why because we trained very well this week, all week.
"To turn up and perform like that as a group is very hard to take."
The game as a contest was effectively over by half-time, as two late tries saw Glasgow lead 27-11 at the break.
Dan Parks also landed five successful penalties in the opening 40 minutes as Gloucester's indiscipline and collective errors left them with a mountain to climb in the final period.
And while Redpath was clearly disappointed with the way his side failed to hit back after the break, he accepts that the damage was well and truly done before his half-time team talk.
"We got the balance of the game wrong in the second half," added Redpath.
"We ended up driving too many lineouts when we should have been trying to get over the gain line to make it easier. When you drive on a small pitch and they've suddenly got more numbers up on their feet, you end up creating a same way situation which isn't challenging the opposition.
"I'm a little bit frustrated on that front but being 27-11 down at half-time is something we need to look at more than any aspect of the second half.
"I think we need to reassess. We've come up here in a big competition that we need to front up in and you can't run away from that.
"Whether you're tired or how many games you've had, it's irrelevant. You've still got to go on the pitch and perform.
"There was some indiscipline around certain areas and Parks capitalized in the first half. So we never really had a chance to get any real field position.
"Credit to Glasgow, they took their opportunities. They looked dangerous on a couple of occasions when they counter attacked. I don't think it was all about us being dreadful, I think some credit has to go to them.
"They manufactured their points better than we did. We were unable to create any pressure because we didn't keep the ball long enough or control the ball.
"There was no complacency or thoughts that it was going to be easy. I know what it's like when you bring an English side to Scotland. That's a fact of life and everyone has to understand that."
