Ospreys coach Steve Tandy hailed the maturity of his young side after they secured a last-gasp victory over Gloucester in the LV= Cup.
Morgan Allen's late try gave them a 33-27 win after the Aviva Premiership visitors led by a point in the dying seconds.
"It was more nailbiting than I would have liked, if we had not come away with the spoils I would have been disappointed," Tandy said.
"It was testament to the maturity the guys showed to try and build for a penalty first and then to go for a try, that was the icing on the cake. They
thoroughly deserved the win.
"We had lots of young guys out there and all in all it was a real positive
night for Ospreys rugby. I probably got a bit carried away at the end because I know what that meant to the group.
"But we had some guys tonight making their debuts or only their first or
second starts and it is something we can feel really positive about."
Gloucester director of rugby Nigel Davies added: "We just didn't manage the game and the conditions well enough. The Ospreys handled that far better.
"We put a lot of pressure on ourselves for a large amount of the time. They
had a better kicking game than us, we had no length and no accuracy with that.
"That was the deciding factor, we need to play the game in the right areas and
we just couldn't do that."
