Ospreys captain Alun Wyn Jones accepts he may not win a European trophy this season, but is proud of the progress his young side are making.
The Welsh region are on the brink of elimination in the European Champions Cup after losing 18-14 to Racing Metro.
Defeat to the French side left Ospreys third in Pool Five, with just one win from their four matches to date.
"I might not get silverware but I'm proud of what we're achieving here and what we're creating," Jones said.
Jones has won three Celtic league titles and an Anglo-Welsh Cup with the Ospreys but is still without a European trophy.
The second row has also had a stellar international career, winning three Six Nations Championships with Wales including two Grand Slams.
Jones captained the British and Irish Lions in their series-clinching win over Australia in 2013.
But a European crown with Ospreys remains elusive for the 29-year-old.
"Personally the frustrating thing for me is we are learning and we are growing," said Jones.
"But at some point the learning has got to stop and we've got to convert that into results. I've been doing this for a long time now and I can take pride from it."
Jones is refusing to give up on his side's chances of progressing in the competition but rued their failure to complete a comeback which had looked unlikely when they trailed 15-0 at half-time.
Ospreys must be more clinical if they are to close the gap between themselves and Europe's elite, according to fly-half Dan Biggar.
Biggar praised his side's display but lamented their lack of cutting edge.
"We showed a huge amount of effort and pride but, ultimately when you came to France, you have to take one or two more chances," he said.
"You look at the budgets between the two sides and we should be nowhere near competing with teams like that.
"That shows the guts and effort we've got, but we need a bit more than that sometimes.
"It's disappointing because we felt we created quite a bit. It's the same old thing, if you don't take your chances, you're very unlikely to get the result you want.
"It was a huge effort for such a young side but we've got to stop using that as an excuse on times.
"Some of the rugby we played was some of the best we've played all season.
"It's all ifs, buts and maybes. The bottom line is we weren't clinical."
Ospreys return to Pro12 action when they host Ulster at the Liberty Stadium on Saturday, 20 December.
"We can't afford to feel sorry for ourselves. We've got to dust ourselves off and get back on the horse for Ulster next week," added Biggar.
"It's a huge game in the Pro12. We have to get back to winning ways."
