Ulster number eight Nick Williams is confident his side will come through their disappointing 9-7 PRO12 defeat to Munster in quick time.
Williams was clearly upset with the team's performance as Ulster missed the chance to close in on Scarlets at the top of the league standings.
But he is determined to bounce back, starting against Oyonnax this weekend.
"If we're going to be frank and honest we didn't play to the standards we require of ourselves, to lose at Kingspan Stadium on Saturday, after all the work that we've done in the last four or five weeks, was probably a bit of a step back," he told Ulster Rugby after the loss.
"But it's not all doom and gloom, this one game isn't going to change the path we're on. Perhaps from the outside it's not so obvious, but we believe in what we're doing, the way we are playing, and we'll come through this."
Williams, who will join Cardiff Blues at the end of the season, believes that errors cost them against a Munster side that entered the game on a poor run of form.
"As Les Kiss has said we like to back ourselves, and we probably played too much 'footy' in our own 20 metres. I was guilty of two or three errors there, and when you try to push things in this day and age mistakes lead to more mistakes," he continued.
"Fair play to Munster, they dug in deep and we knew we had to go to places we hadn't been before. Unfortunately on Saturday we didn't maintain the momentum we've had recently."
He added: "We've got to have an honesty session this week, putting things to bed first and then we'll think about France. There'll be a few questions asked after the result against Munster, but we'll learn from that and from the video sessions we'll all have.
"But this squad is a quality group of players, and one poor performance, one bad result, doesn't put us off-track. Immediately after a game like this against Munster you are a bit 'down', but overall there's a lot to be positive about and when we get this out of our system, been honest with ourselves, we'll be ready and confident for Europe."
