Tuncay Korkmaz insists Deeping Rangers can’t afford to slip up on Saturday.
They face AFC Kempston Rovers at the Haydon Whitham Stadium in search of a fifth successive win.
The Bedfordshire club are five points behind Deeping in mid-table with both clubs aiming for a top-eight finish.
Rangers boss Korkmaz said: “I’ve heard they are quite a physical side who are better than in previous years.
“They are going to be in and around us at the end of the season.
“So this is one of those games where the message is clear – ‘we can’t afford to lose it’.
“We need to make sure we keep it tight and put away our chances.
“They are good enough to be one of our rivals in making a challenge for the top eight.”
In midweek Korkmaz was able to rest a few players as Deeping made comfortable Hinchingbrooke Cup progress with a 3-0 home victory over last season’s beaten finalists Stotfold.
Adam Scotcher marked his return to the attack with the first two goals after seven and 27 minutes.
David Burton-Jones sealed Deeping’s passage to the last eight with 20 minutes left.
Korkmaz added: “It was pleasing to get another clean sheet and we are getting better in each game, although we are not quite there yet.
“Our strikers are hitting form as Adam came in for Jezz Goldson-Williams who was cup-tied after a hat-trick last weekend.”
Deeping rested Jordan Avis, Tom Smith and Thomas Palmer on Tuesday night while Scott Ginty is getting closer to full fitness.
Mohammed Hamid made his debut in last weekend’s win at Long Buckby after the club received international clearance following his spell in Norway.
