Jim Bentley believes form could go out of the window when Morecambe travel to Fleetwood on Saturday.
Both sides have had differing fortunes in recent weeks with the fourth-placed Cod Army as desperate for the three points as the struggling Shrimps.
Bentley is however confident his side can upset the odds at Highbury in the Lancashire derby.
He said: “I’ve been brought up on Liverpool-Everton games and form going out of the window and things like that.
“I don’t think anyone in the country would look at Fleetwood at home to Morecambe and predict anything other than a home win.
“But we’ll go into the game knowing we’ve got enough to upset them. They’ve got strengths and weaknesses but every game brings up different challenges.
“It’s a local derby and the lads will be looking forward to it.
“We’ve got to make sure we run as hard and battle as hard as we ever have done because of the position we’re in and the need for points at the moment.”
Bentley is however also well aware of the prize on offer for Graham Alexander’s side if they finish strongly in the final five games.
He said: “It’s a big game for us it’s a big game for them.
“They’re an excellent side in good form so it’ll be a tough match.
“It’s a derby match, we beat them at home 1-0 on Boxing Day and at the very least they’ll be in the play-offs.
“They’ve got the chance if one of the top three slip up to push for automatic promotion.
“We both need the points for different reasons.”
Chris McCready and Stewart Drummond remain absentees for the Shrimps with Joe McGee and Chris Doyle also set to be missing.
Andy Fleming also starts a three-game ban after his sending off against Mansfield last time out.
Bentley said: “I thought it was maybe a little bit harsh but I can see why the referee has given it.
“It doesn’t look great. Some would (send him off), some wouldn’t, but it’s one of those days where it went against us as most things did on the day.
“He’ll be a big miss.”
