Widnes Vikings coach Paul Cullen has intimated that some of his players are fighting for their futures at the Stobart Stadium.
Cullen spoke out following his side's 30-16 defeat by Leigh on Thursday.
"Some players' effort and performance was absolutely scandalous and not fit to wear a Widnes jersey," he told BBC Radio Merseyside.
"Some players are under an awful lot of pressure. If they don't want to be here, I don't want them here."
Vikings were 24-4 down at half-time in the Championship fixture at Leigh, which left Cullen lamenting his side's first-half display.
"We simply are not working hard enough for each other to build any pressure against any team in this competition," he said.
"Half-time was about trying to find some pride in what was a disgraceful first-half performance," said Cullen.
"Nothing we did in this game can get past how poor we were in the first half and I say that giving credit to Leigh."
Widnes play next at Whitehaven before returning to play in front of their home crowd against Batley Bulldogs on 23 May.
Cullen has vowed to ring the changes before his side's next home fixture, saying: "It won't be about Batley.
"In our preparation it's about getting rid of any element within this club that doesn't want to be here."
