Cobblers' boss Ian Sampson told the press it was their worst performance of the season: "It was a very disappointing performance and that's the worst I've seen us play this season. We got off to a great start but we didn't kick on from the early goal and that was the real disappointing thing.
"We looked lethargic, we lacked sharpness and enthusiasm and if you can't pass the ball to each other then you are going to have problems. I don't think there was any question that the players were not trying but when passes go astray and the crowd are getting on your back then you can lose a bit of confidence. The fans have every right to voice their frustration but the players need to rise above that.
"We are not getting results at the moment so of course I am concerned but it's only us who can turn things around, no one else."
Bulls boss John Trewick was more upbeat: "We've been playing pretty well in the last few matches with the new system. I just tinkered with it tonight, played with a couple of wide men and one centre forward which isn't a great deal different to what we've been doing. With four players in there with fresh legs I wanted extra energy in there.
"The lads played the system well I felt, so much so that Northampton had to change to try to deal with us. Once they'd done that I had to tinker with it a bit again to negate what they'd done and we controlled the game apart from one period."
Speaking about Mathieu Manset he added: "That's what Mathieu can do. He's big, strong, and quick and he's got a good touch. He worked very well up front for us I thought - ran his socks off, as did everybody else. It was a real solid team performance and a very well deserved victory."
