Preston North End boss Phil Brown warned his side they need to get rid of their losing mentality if they are to avoid relegation.
North End slumped to a 2-1 home defeat to local rivals Burnley yesterday which left them 11 points from safety.
Jack Cork headed home an 84th-minute winner after Jay Rodriguez had cancelled out Barry Nicholson's opener for the hosts.
Brown said: "I've got a lot of disappointed people I've got to pick up over the weekend now.
"I've got my staff getting involved with opposition staff on a weekly basis.
"Maybe if the players showed enough fight where that was concerned we might win a game.
"There's one or two prepared to die for the cause and that is what I need on the field as opposed to off it.
"I haven't got an impossible task but it is arresting the losing mentality."
Brown was less than impressed with his side's defending, particularly for Rodriguez's leveller.
"I need them to understand why we are conceding goals," he added.
"The first goal is a nonsense in terms of our defending - we were comfortable up till then.
"It is basic, fundamental defending we have to get right.
"Bragging rights go to Burnley this week and I can't stand the sight of 5,550 supporters enjoying themselves at Deepdale.
"We forgot to play when we got the ball, but we didn't hold the ball up when we got it up front. I need better quality in both final thirds.
"We've got 13 games to try and put that right."
