The Ospreys will hope to build on their seven-try blitz of Ulster when they travel across the Irish Sea to Belfast.

Lyn Jones’ Magners League champions are firmly back in the pool and need another bonus-point victory to maintain the pressure on leaders Gloucester to reach the last eight.

Despite losing in all three rounds of the Heineken Cup so far, Ulster will be backed by a vocal Ravenhill crowd keen for their side to avenge last weekend

And caretaker coach Steve Williams will hope the 1999 European winners can bring a smile to their fans faces by repeating their Magners League home win against the Ospreys back in September.

Steve Williams has named an extended squad to take on the Ospreys at Ravenhill on Friday night. Williams who will name his starting line up from on Thursday at noon said: “We need to look at making a few changes and injecting fresh legs into the team”

Ulster scrum half Isaac Boss spoke after the Ospreys game last week and said  “We have an opportunity to redeem ourselves at Ravenhill next week, it is going to be tough but we have to get back on track and try to start putting the performances in”

Included in the squad is Ballymena man Matt McCullough who if selected this weekend will win his 100th Cap for his province Should he take to the field, McCullough (26) will be one of the youngest players to have reached the landmark 100 appearances for Ulster Rugby and join the elite club which includes names such as Gary Longwell, David Humphreys, Andy Ward and Simon Best.

The Ospreys have named an unchanged line-up for their trip to Ulster in the Heineken Cup on Friday night. 

Lyn Jones’s side recorded a convincing bonus-point 48-17 win in Swansea last weekend against the Irish outfit to keep the pressure on group leaders Gloucester. 

The Welsh region face a much more difficult task across the Irish Sea and fly-half James Hook, who scored 13 points at the Liberty Stadium a week ago, believes the Ospreys are ready for the challenge ahead. 

Hook said: “We’re confident after last week’s great all-round performance and it was certainly one of our best. We know we’ve got three cup finals left and have the ability to win them all, but we also know it’s going to be a huge task. Last season we shipped 40-odd points and were taught a big lesson.

“A lot of us remember the atmosphere and how Ulster play at home. Ravenhill is intimidating and the crowd are right on top of you. They live off that. If we give Ulster a sniff, their tremendous supporters will get behind them and suddenly we’ll be under pressure.

“Ravenhill is a fortress for them so it’s vital we start well and silence the crowd as quickly as possible. Gloucester gained a bonus point in the blink of an eye in Belfast so we know this game is huge for us. We’re optimistic about our prospects. If we can win and get that bonus point, it would set up a massive match against Gloucester next month.”
