Chris Wilder will remind his Cobblers squad that there can be no margin for error as they begin a trio of fixtures against the struggling sides of Sky Bet League Two.
Town are in lava-hot form at present, having won their fifth successive game on Saturday, a hard-fought 2-1 victory over Morecambe at Sixfields.
They head to Hartlepool on Tuesday night to face a side who are nine points adrift at the foot of the table, before a trip to 20th-placed Mansfield and a home game against second-bottom York City.
Wilder’s team are now just five points off the play-off places and while they are growing increasingly confident with every victory, the manager knows they must maintain performance levels as though they are playing knockout football.
“We don’t have the luxury of not being able to win every game now, like the top sides in the league will have,” he said.
“Really, we’re playing play-off semi-final or cup-tie football every time we go out at the moment and we don’t have any room for any mistakes.
“We’ve got another big week coming up and it doesn’t mean anything that we’re playing teams at the bottom because we know from our situation last year how hard those games can be.
“No team really fancied us when we got our fighting spirit going and so the next three games will be really tough for us.”
Wilder is likely to be without defender Zander Diamond, who limped off on Saturday with a pulled hamstring, for the trip to Hartlepool but Ryan Cresswell is available again after suspension and is likely to return to the starting side.
“He (Diamond) has had a problem with his hamstring and it was tight,” confirmed Wilder. “
That’s our first injury since the New Year so that’s really disappointing for us and for Zander.
“I thought Ben (Tozer) was excellent when he came on. We also had a bit of a problem with Brendan Moloney, who was sick before the game but put his hand up to play.
“Marc Richards has got a bit of a hip injury as well but we’re on a decent run and everyone wants to play.”
