Wakefield come into the game having beaten Hull FC last week and boss Daryl Powell has the belief his side are due a big performance.
Speaking to BBC Radio Leeds, Powell said: “We’ve won two from four in the league which is an alright start I think. But if you look at us at the moment, I think we can play much better.
“Leeds have hit the ground absolutely flying and they’ll be pretty big favourites for this game I would say.
“For us, I think there’s a really good game right around the corner and you’d like to think it’s in this game.”
Wakefield most recently reached a Challenge Cup final in 1979 but the club have recent Wembley pedigree.
Powell led them to victory in the 1895 Cup against Sheffield Eagles and would love to steer them to the national stadium again.
“It’s awesome for players to go and play at Wembley and still is. I know there’s bits and bobs about crowds but that’s the fans, for a player I think it’s unbelievable to get to Wembley,” Powell added.
“We had a taste of it in the 1895 and you’ve only got to look at what did to the crowd and how they came out to support the team.
“We had more there than Warrington that day I think. It’s still revered, it’s all about pounds, shillings and pence and how hard it is for fans to pay to go to the games.
“The challenge for us is that we had a tough draw last year and this year is a tough draw and we’ve got to be tough enough to get through.”
