He said: "Players must maintain their focus and we will be aiming to win the game and win it well.
"If we can get the four tries for a bonus-point we will put pressure on Perpignan and that's all we can do."
Perpignan are currently favourites to qualify for the quarter-finals ahead of Warriors thanks to a superior try-scored record during the matches between the two sides.
But, according to Redman, the Sixways side will be making sure they pick-up ten points in their last two games, even if the French side do the same.
He continued: "There will be a big emphasis on individual performances and players will make sure they are pushing each other for selection in the LV= Cup and Aviva Premiership, so I expect big victories in the next two games.
"We have made changes to the side which faced Leicester and we want to see a high level of accuracy when it comes to passing, catching and set-pieces."
Rovigo have lost every game in the Amlin Challenge Cup this season and were beaten twice by Bizkaia Gernika in December, despite having more European experience than their Spanish opponents.
And Redman admits he didn't expect the Italian side to only have one point at this stage of the competition.
He added: "Rovigo have a very proud past and they have a lot of good players so I am surprised they haven't been so competitive this year.
"But they are playing at home on Saturday in front of passionate supporters so they will want to put in a good performance against us. With that in mind, it's vitally important for us to be mentally and physically prepared."
