Kiss: Huge week for Ulster
Trailing 0-23 at half-time, the Ulstermen silenced the buoyant crowd with tries from Rory Scholes, Craig Gilroy and Kyle McCall to setup a tense finish.
And just when his team needed him most, Paddy Jackson stepped up to land the match-winning penalty.
The victory cemented Ulster's second placed standing in Pool One, ahead of a crunch encounter with Saracens and a home clash with Oyonnax.
Saracens are one of only two teams to win every match so far in this season's Champions Cup, and Kiss knows the size of the challenge ahead.
"We have a chance, without a doubt,: Kiss said.
"It's a massive week for us, next week, not an ideal one.
"Saracens got beat at the weekend by Harlequins, so they'll be smarting.
"It doesn't get any easier for us, but we're in the hunt, and that's the main thing.
"We need to get points out of next week somehow, and we need to deliver a lot better at home against Oyonnax in the next match. At least there's a chance for us.
"It was just a moment that we just had to stand up and take responsibility and own the drivel that we put out – and, to a man, they put their hand up.
"A couple of replacements were made, and I think they had to be made, although I do feel for the guys we replaced because the team as a whole didn't do them a favour.
"We were very loose in that first half, with chest tackles, missed tackles, getting the ball ripped out of our grip. When the ball was on the ground we were trying to hack it away rather than diving on it."
