Super League’s two in-form teams meet at the Halliwell Jones Stadium on Thursday when Warrington host St Helens in the opening game of the Super 8s.
The top-four play-off places appeared to be a foregone conclusion a couple of weeks ago but Saints’ five game winning streak along with Catalans’ loss of form sees Keiron Cunningham’s side sit fourth heading into the final seven games.
Furthermore, St Helens put in their most impressive display of the season in both attack and defence last time out beating local rivals Wigan 23-4.
Warrington also head into the game full of confidence following last Saturday’s 56-12 thrashing of Wakefield in the Challenge Cup semi-final.
The win, which booked their place at Wembley later this month, stretched Wire’s unbeaten run to seven matches in both league and cup.
A narrow 34-30 victory over Huddersfield in the final game of the regular season ensured Warrington finished second and the Wolves can climb above leaders Hull FC temporarily with a win.
Head coach Tony Smith makes two changes from the semi-final squad with Joe Philbin and Sam Wilde replacing Ryan Bailey and Kevin Penny.
Meanwhile Dominique Peyroux is set to make his first appearance for Saints since May replacing Shannon McDonnell.
St Helens came out on top 25-22 winners when the sides last met at the Halliwell Jones Stadium in April but Warrington avenged the defeat with a 26-4 win at Langtree Park in June.
