Ulster director of rugby Les Kiss believes his side has "a massive week" ahead of them as they prepare to face Saracens in the Champions Cup.
The province came from 23 points down to beat Oyonnax last week, which keeps their hopes alive of making the European knockout stage.
They are now six points behind Saracens ahead of a trip to Allianz Park and Kiss admits they face a mammoth task going to the English side.
"We have a chance, without a doubt. It's a massive week for us, next week, not an ideal one. Saracens got beat yesterday by Harlequins, so they'll be smarting," he told EPC Rugby.
"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."
He added on their come-from-behind win in France: "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."
