Tyrone Holmes believes Glasgow Warriors have what it takes to go further in the Heineken Cup after
Holmes and Tim Swinson both scored second-half tries as the hosts bounced back from last week's defeat by Toulon.
"If we weren't confident, if we didn't believe it, we wouldn't be here," said the South African forward.
"We are going to keep working hard and that's the plan - to get out of the pool."
The Warriors were trailing 9-6 at the break after Ruaridh Jackson and Gareth Steenson had exchanged penalties.
However they took control in the second-half, with Dave Ewers late try not enough for the visitors at a rain-soaked Scotstoun.
"It wasn't as free-flowing, but you've got to adapt to the conditions," said Holmes.
"Obviously there were lots of mistakes, something you can't plan to deal with.
"I think, second-half, we just decided to keep the ball, keep it tighter, work with the forwards, get over the advantage line - that's where the space was - and we managed to do that."
The 27-year-old joined Glasgow in the summer having previously played for Stormers and Western Province. His try in 71 minutes finished off a sweeping move involving DTH Van Der Merwe and Byron McGuigan.
"It was just great play from the backs and I was just lucky enough to be on the end of a good back play," he said.
"I think that's what we need - a tough opposition to get us together, get us working as a 22.
"We've dug deep, got out of a dark place. I think it's good to move forward with a bit of momentum."
Head coach Gregor Townsend said he was always confident his men would bounce back to claim the points, despite being below par for much of the first half.
"I was pretty happy with how the game was turning out," he said. "We gave away a couple of pens, maybe we were too eager, but as the first half went on we were getting better tactically.
"It was one of those games where we come in at half-time losing and things aren't going our way, but I thought with the way we were playing we would get back ahead.
"It's a tight group now. Everyone has had one win and picked up a bonus point up. It's a cracking pool."
