Castleford Tigers will be hoping to make it four wins from four when champions Wigan Warriors visit The Mend-A-Hose Jungle
Darryl Powell's men have been the surprise package so far as they have been impressive in dispatching the likes of Bradford, Catalan and Hull KR in 2014.
Wigan have just had the two Super League games due to their participation in the World Club Challenge and they returned to winning ways against Wakefield last time out after dropping their opener to Huddersfield.
Powell have made just the one change to his 19-man squad with Nathan Massey, who is fit against after a groin injury, returning in the place of Jamie Ellis "There are a lot of big challenges ahead for us," Powell told Boots 'n' All. "We are not going to get too carried away, we're going to focus on every single week and get players improving on a daily basis.
"They are all competing hard across everything that we do at the club; we've had a great start and it's given us a really good platform, but there are tough challenges to come starting with Sunday [against Wigan]."
Wane opted to rest of number of his stars that featured against the Roosters against Wakefield and he has made five changes for Sunday's clash, which he has described as their biggest test so far.
Captain Sean O'Loughlin has dropped out of the squad along with youngsters Dom Manfredi, Ryan Hampshire and Connor Farrell while Greg Burke joined Bradford Bulls on loan earlier this week.
Josh Charnley, Dan Sarginson, and Matt Bowen all return, while Eddy Pettybourne has completed a one match suspension. Jordan James also comes in and is poised to make his first Wigan appearance since May 2006.
"They can hurt you, they have won all their games and they can play some fantastic rugby," Wane told the club's official website. "You look at Liam Finn who has come from the Championship, he has acquitted himself really well.
"They have some really good players and it is a difficult place to go mentally and our players need to rise above that and go and perform. I will pick my best team for Sunday because this is our biggest test so far."
Castleford Tigers: Dixon, Shenton, Carney, Dorn, Sneyd, Lynch, Milner, Huby, Millington, Hauraki, Massey, Clark, Holmes, Mariano, Wheeldon, Owen, Channing, Fleming, Finn.
Wigan Warriors: Bateman, Bowen, Burgess, Charnley, Clubb, Crosby, L. Farrell, Flower, Gelling, Green, Hughes, James, McIlorum, Pettybourne, Sarginson, Smith, Taylor, Thornley, Tomkins.
