Castleford Tigers' dominance of Super League in 2017 was reflected in six Dream Team selections when the side was announced on Monday.

Man of Steel nominees Zak Hardaker and Luke Gale are joined by Greg Eden, Michael Shenton, Grant Millington and Mike McMeeken in the 13-man line-up.

St Helens contributed one player - centre Mark Percival - to the side.

Castleford Tigers rested a lot of players for their final Super 8s game and make a whopping nine changes from the side that lost 48-16 to Hull FC last time out.

Key half-back Luke Gale makes his return to the Castleford side, less than three weeks after having an appendix operation.

Castleford: Hardaker; Minikin, Webster, Shenton, Eden; Roberts, Gale; Massey, McShane, Sene-Lefao, Foster, McMeeken, Milner.

Replacements: Millington, Moors, Cook, Springer.

St Helens make two changes from the side that beat Salford 30-4 seven days ago.

England duo Jonny Lomax and Matty Smith come in for Theo Fages and Danny Richardson.

St Helens: Barba; Makinson, Morgan, Percival, Grace; Lomax, Smith; Douglas, Roby, Thompson, Knowles, Taia, Wilkin.

Replacements: Walmsley, McCarthy-Scarsbrook, Peyroux, Fages.

St Helens may be a team in form but, for their coach Justin Holbrook, there's no doubting that semi-final opponents Castleford have been the stand-out side in Super League.

"Right from round one they've shown it," he told BBC Radio Merseyside. "That's why they sit so clear at the top.

"However, we're the real improvers, we've got better and better every week and we're in a real good position. We're here now and want to carry on."

Castleford dominated the Super League competition in 2017, wrapping up the League Leaders' Shield with four games to spare, but that counts for little tonight.

"It's a one-off game, with a team coming to our ground and trying to knock us off," head coach Daryl Powell told BBC Radio Leeds.

"We've a lot of pride in how we've played this year and this is a perfect opportunity for us.

"They're playing well and have the addition of a superstar in Ben Barba. We've got to turn up and deliver our best performance. We're confident but mindful of Saints."

Castleford Tigers are 80 minutes away from a first Super League Grand Final in their history, although 10-time veterans St Helens stand in their way.

The Tigers lost to Wigan in their one Old Trafford visit - the 1994 Premiership final - while the Saints have won five and lost five of their Grand Final visits.

Tigers' Man of Steel nominee Luke Gale will have a late fitness test after recovering from an appendix operation.

Their final league game against Hull FC saw a host of key players rested, but Zak Hardaker, Nathan Massey, Grant Millington, Adam Milner, Junior Moors and captain Michael Shenton all return for this knock-out semi-final.

The Saints are unchanged from the side that has won the past two games.
