Warriors lock heads with Bourgoin at Sixways Stadium on Saturday (kick off 3pm).
Director of Rugby Ruddock has ordered his team to banish the memories of last week with a spectacular performance on their home turf.
"We weren't particularly pleased with our performance in Bourgoin and obviously that result means we face a massive game here," said Ruddock.
"We need this big performance to turn around a couple of defeats now and get some good home momentum before the Bristol game.
"We were certainly chasing the game from the first moment and it didn't go well for us from that point. We really let ourselves down, let the fans down and we need to put that behind use for a big performance at the weekend.
"But it's still really in our hands. It's for us to lose rather than anyone else to win. We want a big performance in front of home fans to really dominate the group - we've got a chance to do well on Saturday."
Ruddock has also announced that some of his star names could well be rested this weekend to ensure that he has his best team ready for Bristol the following week.
'I said a number of weeks ago that we are going to rotate our squad a little bit for the European Challenge Cup matches so we arrive into the next round of the Guinness games with the players that have had the opportunity to rest, they will be key players for us," he added.
"There will be a couple of changes for example I think Greg Rawlinson will probably be rested this weekend, Matt Mullan could well be rested.
"Hal Luscombe is looking to figure he should be in the 22, that's great news to finally have him in contention."
