Wigan Warriors coach Shaun Wane is looking for a response from his players after cracking the whip in the wake of his side's shock First Utility Super League defeat at relegated Bradford Bulls.
Wane, who says he had a sleepless night after the champions' 16-8 loss at Odsal on Sunday, cancelled the players' day off on Tuesday and ordered them in for extra training ahead of Thursday's home game against Salford Red Devils.
"I didn't sleep," he said.
"I did the review about four times and I've been through it with the players who know where we're at and where we need to improve.
"I don't expect to see that performance again. We need to have the attitude that we've had all season.
"They were in again on Tuesday which was a day off. We are a win-at-all-costs club and, when we don't win, there's an inquest. We have a very honest group of players and I'm sure we'll see a different attitude."
A win for Wigan will take them to within two points of leaders St Helens, who go to Hull FC on Friday, while 11th-placed Salford need the win to keep alive their hopes of claiming the final play-off spot.
Wane is expected to give England second rower Joel Tomkins his first appearance since rejoining the club from a two-and-a-half-year spell in rugby union.
The 27-year-old returned to his home-town club from Saracens six weeks ago with a back injury but is now fully recovered and is set to provide the champions with a timely late-season boost.
Tomkins is likely to go up against his youngest brother Logan, the 21-year-old hooker who is on a season-long loan with the Red Devils and among several familiar faces returning to the DW Stadium.
Salford, who lost 25-4 at home to the Warriors in May, are coached by Wane's former assistant Iestyn Harris and, although Gareth Hock is suspended, his back-row colleague Harrison Hansen will return to Wigan for the first time since his move to the AJ Bell Stadium.
"There is a lot of Wigan about them," Wane said.
"They look like us when they play. Their coach has gone over with a lot of information from me to try to make Salford better. We cancelled each other out for long periods of the first game and I'm expecting something similar.
"They are coming on the back of a bad loss like we are, so there will be two evenly-matched teams.
"Obviously Rangi Chase is doing his thing and I have loads of respect for Harrison Hansen and Logan Tomkins, who played 80 minutes last week.
"They've got some quality. Their owner has done a great job in going out and hand-picking some of the best players from all over the world and he is demanding results."
