Wakefield coach Chris Chester has admitted the club are looking to make a couple of signings within the next few weeks.
Trinity were hammered 46-16 by Wigan at the DW Stadium on Thursday night.
Wakefield have lost eight of their last nine matches and currently sit eighth in the Super League table – two points above Huddersfield, Leeds and Hull KR.
Speaking after their loss at Wigan, Chester said: “There are too many individuals not playing good enough and too many players not wanting to help their team-mates out and that’s not what we are about.
“Attitudes have got to change and our approach to games have got to change.
“That first 40 minutes was probably the worst half we’ve had since I’ve been in charge at this club.
“I think we need a couple of new faces. We are being forced to play players out of position, Joe Arundel is not a back-rower but he had to play there.
“We need to find some energy from somewhere, whether that is playing some academy kids because there are some players that just aren’t playing good enough for this team and if we had a few more bodies, they’d probably be sat on the sideline with me.”
Chester revealed three weeks ago that he thought Wakefield were in a relegation battle, and he now insists they need to treat every game as a cup final.
Trinity face a tough run in as well as they face top five sides St Helens, Hull FC, Wigan and Warrington in the remaining six rounds.
Chester added: “We are going to have to treat every game as a cup final now.
“Whether we try to dress it up or not, we are in a battle. I said to the guys after the game that we’ve all got wives and kids, we are all in it together and we’ve all got mortgages to pay. We need to find a fix very quickly.
“The players have got five days off now because of the Challenge Cup semi-finals and they need to use these five days to refresh their minds and think about how they can help this team over the next six or seven weeks.
“We are in a dog fight and we need to quickly turn that around because games will come quick and fast after the Challenge Cup semi-finals.
“I’m confident in the players but I think we need some fresh bodies to come into the team. Hopefully we can get a couple of fresh bodies over the next couple of weeks.”
