Aidy Boothroyd stressed the importance of the clean sheet the Cobblers gained in their goalless draw with Morecambe at Sixfields.
Town shared the points in a 0-0 stalemate with the Shrimps in which the best chance of the game fell to former defender Mark Hughes, whose header was cleared off the line by Darren Carter.
There was little in the way of attacking intent from the home side, who even reverted to a 4-5-1 formation for the final quarter of an hour of the game, with Ivan Toney - on his full debut - coming closest to scoring.
The attacking threat was diluted by the loss to injury of Jacob Blyth (thigh) and Clive Platt (calf) in training on Friday, putting the emphasis on the defensive end of the field.
Northampton secured a first clean sheet of the season but only a fifth league point, a return that ensures they remain in the Sky Bet League Two relegation zone.
But Boothroyd was pleased with the resilience shown by his players against a talented Morecambe outfit.
“We want to win every game we play in but we had to be valiant against a team in good form and who were seventh in the league before the game,” he said.
“The past week has given us a bit of adversity with injuries and I’ve never lost three players in a week before like we have this past week so it’s really testing us.
“I thought we were the dominant force for long periods but we know we have to score when we are having our periods of dominance.
“Until we start to get some people back we are going to have to grind out the results and it was very important we got a clean sheet out of this game.
“I don’t think Morecambe looked like scoring, our centre-backs were excellent and there was only one team that was going to get a goal and that was us.”
