Jonathan Humphreys praised the commitment and character shown by his Ospreys side after their 30-14 defeat by Toulouse.
The RaboDirect PRO12 champions have been struggling badly with injuries in recent weeks but Humphreys will take plenty of positives from the match despite the likelihood that they will drop to third in Heineken Cup Pool 2 on Sunday.
"We're very proud of the boys. We could have improved on a few things tactically but we could not have improved the effort - that was as good as it gets," Humphreys said.
"We had six guys making their Heineken Cup debut and I thought they were outstanding.
"With the amount of set-pieces they had in our half you would have expected the score to have been heavy, but in the end I don't think it did us justice.
"We are disappointed because coming in at 12-7 at half-time we should have been in front. We created a lot of pressure and they were ragged.
"In the second half we wanted to get down their end and create some set piece pressure but we weren't able to do that.
"We felt we could have a real crack and if we could have just executed better a few times it could have been a different story.
"This is a disappointing result but we're looking forward to next week. It's all about recovering and seeing if we can do ourselves justice in the home leg.
"We can still have a big say in this tournament. We have Toulouse to come down to the Liberty Stadium and Leicester so it is important that we do ourselves justice."
