The bonus point from the defeat gave Glasgow their best Heineken Cup finish for 14 years but with the Warriors going well in the RaboDirect Pro12 they wanted to make their mark in European competition.
Chris Cusiter told the Scotsman: “We showed our character in the second half to play the way we did, really upped our intensity and got ourselves to 18-17 playing really good stuff and it was frustrating they managed to go on and win the game because we had done so well to get back ahead.
“That 20-minute period in the second half was the best we have attacked for a few weeks. The pace and intensity – they couldn’t live with it for those 20 minutes but unfortunately the game is not played over 20 minutes.
“It is trying to get us as a squad playing with that intensity. It is hard work and it is tiring, but they could not live with it, so we have to replicate that for 80 minutes and then we can win at places like this.
“We have played well in part of this Heineken Cup, but I genuinely thought we had a squad who could have qualified for the quarter-finals of the Heineken Cup or the Amlin and we did not do that.
“We have to look at that and why we were not good enough when it mattered.”
