Holbeach United manager Tom Roberts has promised changes and demanded a response to get their title bid back on track.
The Tigers take on unbeaten leaders AFC Kempston Rovers at Carter’s Park on Saturday with a 13-point gap down to the fifth-placed hosts.
Holbeach have two games in hand but they are yet to face any of the top three teams so far this season.
The trip to Kempston was called off three weeks ago and has not yet been rearranged.
Roberts’ side will meet Leicester Nirvana twice next month followed by both games against Newport Pagnell Town who are currently third.
But the Tigers need to find top form again to revive their challenge in the ChromaSport & Trophies United Counties League’s Premier Division.
We are going through a little blip having started the season so well but the lads have got to work harder.Tom Roberts
Last weekend’s 3-2 defeat at Northampton Spencer was a third loss in four games over the past two months which also featured a winter break due to the weather.
Roberts said: “I told the lads after Saturday’s game that they have got to take responsibility for how they look after themselves.
“They didn’t work hard enough and on the day it even looked like they had never played with each other.
“That was disappointing and so frustrating.
“I don’t know what was going on but we can’t afford to miss that many chances.
“We gave away silly goals, although Spencer worked hard and sat in defensively at times to put their bodies on the line.
“We are going through a little blip having started the season so well but the lads have got to work harder.
“Kempston are flying at the moment and their confidence will be high coming here. But Saturday is all about us and putting things right.
“There will be changes within the current squad as we can’t keep going along like this. I need to freshen things up.”
Roberts is ready to hand a full debut to on-loan striker Sean Coughlan after a couple of substitute appearances.
The teenager, who joined from the Stamford-based FootballCV Academy, came off the bench to score on 88 minutes at Spencer.
Roberts added: “He was a real positive last Saturday and he’s now pushing for a starting place. Sean has got a lot of ability.”
Jamie Stevens completes a three-match ban and Stacy Cartwright is available after a two-game suspension. Nick Jackson and Tom Gosling are both banned.
Former Tigers winger Ash Fuller is part of Kempston’s squad which beat Nirvana 2-0 last weekend to knock the Leicester side off the top of the table for the first time since September with Rovers’ fifth successive league win.
