Matt Dufty played in last season’s final at Wembley and had an incident-packed 80 minutes – sin-binned within the opening five minutes and then scoring a late try to give the Wire hope of a comeback against Wigan.
A year on, he admitted his side were overawed by the occasion and let the pressure of playing at Wembley get to them.
“For us, last year we probably beat ourselves in the first half. The occasion probably got to us a little bit,” he told Sport.
“We lost the game before we even got going. This year hopefully we can start with a level head. We can go in with a clear mind, clear gameplan and stick to it.
“Hull KR are probably the in-form team at the minute and they’re going to be confident. We’ve got to go in and put our best foot forward.”
Warrington have fared well in the Challenge Cup, beating St Helens and Leigh Leopards on the way to reaching this year’s final, but they have been inconsistent in Super League and are currently eighth in the table.
“For us, our gameplan has probably been a bit disrupted this year. We haven’t had a spine that’s been playing all year. We’ve had to figure out things on the run and change up gameplans week to week,” he added.
“Hopefully with George Williams and Marc Sneyd there, we can have a bit more of a structured gameplan and strike where we need and where we want to.”
