St Helens come into the game after they brought home two points from a thriller in Perpignan, during which Jonny Lomax scored the winning drop-goal.
Paul Wellens’ side have come off second best against the Wire in recent times, but he believes they will have learned from their experiences.
“We know they’re a quality side who are very well coached and we’re going to have to play well,” he told Radio Merseyside.
“We’ve been on the wrong end of the results recently but when you look at the last two times we’ve played them, one was a golden point victory for them in the play-offs last year.
“The other one a couple of weeks ago was a 14-12 victory which indicates that there’s not a lot between the two teams.
“Quite often these games are decided by fine margins. We’re prepared for what will be an extremely tough game but also they’re a team where we believe we can go there and win.”
As for whether he will radically alter his plans for Sunday’s cup tie, Wellens was more reserved.
“You learn lessons from every game but in particular when you play teams repeatedly in a short space of time which ourselves and Warrington have, you try and find little ways where you feel you can get joy,” he added.
“They will be no different. Not a lot will change from both teams in terms of personnel but no doubt there will be a few tactical tweaks here and there because teams get a good look at what you’re doing and see how they can exploit that.
“You need to be adaptable and do things a bit different and you might get some results from it.”
