Tipuric makes no excuses
Captain Justin Tipuric branded Ospreys' performance unacceptable after they crashed out of the Heineken Cup with a 36-5 thumping at Biarritz.
It was their second highest losing margin in Europe behind the 43-9 hiding they suffered at Munster in the quarter-finals three years ago.
"We know we didn't do ourselves justice. We let ourselves down, we let everybody down really," said Tipuric.
The Swansea-based Welsh side shipped two early tries and failed to impose themselves on any area of the game except scrummaging.
"We knew it was going to be tough to get back in it if we gave them an early start but that's what we did," said the 22-year-old flanker, who is Sam Warburton's understudy in Wales' Six Nations squad.
"As players we want to win every game. We set ourselves high standards but we didn't reach them.
"It's quite hard to say what went wrong. We will have to watch the footage. We know what we could have done. At the end of the day, you have got to win these games but it didn't happen.
"It wasn't what you expect from a team of our capability - we have let our fans down."
Ospreys director of coaching Scott Johnson, who leaves at the end of the season to become assistant to Scotland boss Andy Robinson, said: "We knew it was going to be a hard day at the office because they started so well and us so poorly. When you have got that sort of tidal wave coming at you, it's hard to stop."
Outstanding Biarritz captain Imanol Harinordoquy said: "We played some of our best rugby of the season to win a European quarter-final. We're happy with the result because we knew the Ospreys are a strong team. They beat us narrowly in Swansea but this made up for that defeat."
