All Black legend Justin Marshall sent out a chilling warning to Ulster today, claiming the Neath/Swansea Ospreys were ready to "get rid of their Ravenhill demons".
Despite the Ospreys seven-try romp over Ulster at the Liberty Stadium, Lyn Jones' side know they must secure another bonus-point victory at Ravenhill this Friday night if they are to stay in touch with pool leaders Gloucester.
The Ospreys have bitter sweet memories of Belfast, losing their opening Magners League game back in September and receiving a 43-7 stuffing in 2006, but in contrast also racking up successive wins in 2004 and 2005.
The Heineken Cup clash is likely to bring a greater intensity than any of their previous visits however and scrum-half Marshall is promising a big display.
"We don't have a great history really of performing well out there (Ravenhill)," he said.
"They will be wounded, but, ultimately, if we are going to progress out of this pool, we are going to have to get rid of the demons.
"We will go out there with the confidence and attitude we had at our stadium and, hopefully, things will follow on from there.
"We have got the side and we have got the ability to test the best players in Europe, and we have to make the best of what we have got left in the pool.
Marshall added: " We have just got to keep on doing what we are doing. We are still in the pool, we are not out of it by any means.
"The performance against Ulster shows we are capable of beating anyone. The pressure was on us with them sitting at the bottom of the table, but we got the bonus point and we didn't have to play sevens to get it."
Ulster flanker Neil McMillan may be available for Friday night's clash, which would ease the back row crisis that forced Matt McCullough to play No 8.
