Worcester director of rugby Gary Gold thinks their 53-38 triumph over Cardiff Blues in the Anglo-Welsh Cup will inspire confidence in his team.
Saturday's victory was the Warriors' first on the road this season and Gold was delighted his opening match in charge ended in a success.
"When you're in a situation like we're in, to go away from home and get 50 points against a team of Cardiff's stature is great," he told Worcester Warriors' official website following their pool win. "I am really happy for the guys and every little bit of confidence will help.
"A win is always good. It wasn't the neatest performance but if you'd have given me 50 points away from home when I was on the plane last week, I'd have taken it."
Worcester scored eight tries on Saturday but after leaking five, Gold knows they have work to do in training to tighten up their defence.
"There were a lot of good things but there is still plenty for us to work on," he added.
"The manner of some of those tries conceded were quite soft. Two of them came after long passages of good defending so there's a defensive resilience we lack at the moment.
"We are good for a few phases then make errors and slip off tackles and we can't do that against Saracens next weekend."
He continued: "Saracens won't give you an opportunity to score 50 points so we must sharpen up our defence. We have a lot of work to do but at least we can get to work off the back of a win.
"They are the best team in Europe. They are the Premiership and European champions and are on song to repeat that again. The challenges don't get any easier and that's why the Premiership is as tough as it is.
"The guys will have no doubt about the magnitude of the task but we are at home and I'd really like to appeal to the Warriors fans to come out in their droves to watch a team that are improving.
"If we get a full Sixways and the guys understand how much they have to tighten up, we can get a good performance."
