Lee Clark said Blackpool have no room for error tomorrow if they want to have any hope of staying in the Championship.
The Seasiders welcome Nottingham Forest to Bloomfield Road currently 10 points adrift at the bottom of the table.
With games running out the chances of avoiding the drop are fading by the week and the Pool boss says his side simply have to beat Forest tomorrow.
“It’s must win if we are going to give ourselves a chance,” he admitted.
“In my own mind I wanted a minimum of four points from these two home games but obviously we didn’t get any the other night.
“We are hurting, everyone in the club is.
“We are in the business of trying to win football matches but we still aren’t out of it.
“It’s obviously becoming harder as we have fewer games to try to achieve that but we won’t give up.”
Forest have been handed a new lease of life in recent weeks after Dougie Freedman replaced Stuart Pearce as boss two weeks ago.
Since then they’ve won two out of two, including a 3-0 win over Wigan on Wednesday night. And Clark knows just how tough tomorrow’s game will be.
He said: “Forest have had two good wins lately and have very good wide players.
“I’ve worked with one of them, Chris Burke, who’s a very talented footballer and a modern day wide player.
“They also have Michail Antonio who has crazy pace down the other flank.
“They are a team full of confidence after two wins under the new manager so we’ll have to be ready.
“We need to continue with a lot of the good things we did on Tuesday and improve from there.”
Pool host their second game in five days tomorrow, although home advantage isn’t something they’ve really made the most of over the course of this season.
Another protest is planned by supporters against chairman Karl Oyston but Clark says it’s something he and the players have to try and put to the back of their minds.
“It’s tough as every game we play at home the anger around the place can be tough for the players,” he said.
“We just have to get our head down and get on with the job.
“We have to try and stay in the Championship. Although it’s getting tough I still think we can do it.”
