Glasgow Warriors are still looking for their first Pool 4 but will face an Ulster Rugby side full of conifidence when the two sides meet in the all Pro12 clash at Scotstoun Stadium.
The Scottish outfit will be looking to build on their impressive display against Northampton Saints which saw them lose 24-15 at Frankin Gardens and just miss out on a losing bonus point.
The Warriors pushed the 2000 Heineken Cup winners and 2011 finalists all the way in the Pool 4 opener last weekend, but will be wary of the threat posed by Ulster, last year's finalists.
Gregor Townsend, the Glagow coach, didn't pull any punches or hide his disappointment in his side's opening defeat but also believes his side can beat Ulster on their home patch in their debut tournament match at Scotstoun.
"We're all massively disappointed not to have won the game," said Townsend, the former Scotland international.
"We put ourselves in a position to do so with some great work in the first 30 minutes, where we took them on in their areas of strength and really had the edge.
"In every game, and especially away from home in the Heineken Cup, you need to play for 80 minutes, and we know we didn't do that.
"Our defending off a couple of their set-pieces wasn't as good as we'd expect, and at a time when we should really have been looking to press home our advantage, we ended up being up against it.
"Those first 30 minutes are what we're all about, and if we can produce that against Ulster, we know we're more than capable of securing the victory we need."
The Irish province cruised to a comfortable bonus point victory over French side Castres at Ravenhill. Ulster raced in for six tries to underline their ambition to lift the Heineken Cup for a second time.
Back row duo Stephen Ferris (back injury) and Nick Williams (rib injury) missed the home victory over Castres but are back and named in the extended squad for the trip to Scotland to give Ulster a real boost.
