Opsreys fly-half Dan Biggar has admitted that his side need to learn from the errors that they made in their defeat to Racing Metro in the European Champions Cup.
The Welsh side fought back after a poor first half and got to within a point of their French opponents, but a late penalty secured Racing the victory which makes qualifying for the knockout stages difficult for Ospreys.
Biggar has insisted that they will feel sorry for themselves, telling reporters: "I'm not sure how to sum up that game- it was crazy. With all the yellow cards, length of the field breaks by both sides, it all got a bit mad.
"I think we actually edged the game. It was a game of two halves- they were better in the first and we had the second. But we're hugely disappointed because of the tries that they scored and the fact that we didn't take our chances."
Ospreys sit third in Pool 5, and trail Northampton Saints and Racing Metro with two games remaining.
