Former Heineken Cup champions Ulster will look to redeem themselves for their fans at Ravenhill next weekend in the return match against the Ospreys.
Vice captain Isaac Boss admitted they were disappointed with their defence after leaking seven tries to the Welsh side and they aim to get back on track sooner rather than later.

"That was not a pleasant experience," the Ireland scrum half admitted at the Liberty Stadium.
"We came here hopeful of getting a result but it did not happen, we are disappointed for the fans who came over as well.
"They got a lot of momentum and scored some great tries, but we were soft in defence and let them come to us a wee bit.
"We will attempt to redeem ourselves next week, it is going to be tough ut we have got to get back on track and start putting the performances in.
"We are not in a good patch at the moment and we are trying really hard to get ourselves out of it, but things are not going our way and we need something to get confidence back up."
