As the squad prepare to travel to Mansfield Town on Saturday, Paul Anderson says last Saturday's win over Forest Green Rovers gave the squad a massive lift.
A single goal was enough to secure maximum points against the fellow promotion chasers, and Anderson admits that was a big result.
"The game against Forest Green was a big test for us and we put on a very professional performance," he said.
"Forest Green play some good football and they showed that but we dug in and threw our bodies in the way and got the result we needed.
"It was a big win. I don't think we realised how big until after the game, but both in the context of the league table and in terms of bouncing back from the defeat at Exeter, it was a big win.
"We felt, apart from a 10 minute period, we did well at Exeter and should have got something from that game, so it was important we responded well last week."
Anderson was a late addition to the Cobblers squad this season, arriving as a free agent in October, but he says he is loving life back at the PTS Academy Stadium.
"I am really enjoying my football at the moment," he confirmed.
"I am loving playing in the new role and the Gaffer has put a lot of trust in me and I hope I am repaying that. I am happy with where I am at, I would love a goal or two but I'm sure that will come. As long as I am helping the team, that's fine by me.
"I will only get fitter and sharper the more I play and I am just working as hard as I can to help the team and hopefully I will be able to stay in the team. That's as far ahead as I am looking.
"When I arrived, I was just desperate to get playing again. From a selfish point of view, it was an opportunity for me and to be joining such a good squad was just an added bonus. It us took a few games to gel but I thin we have really kick on in the last few months and we have real strength in depth.
"Everyone, both on and off the pitch, is pulling in the same direction and fighting for the cause and that gives us a great chance."
As for Saturday's game, against a former club, Anderson is under no illusions that it will be difficult.
"Mansfield are an ambitious club and they will be tough opponents tomorrow," he said.
"They have a new manager and they will want to climb the table but it is up to us and we have to focus on what we are doing and make sure we go out and put in a good performance.
"Christmas is a busy period and momentum is important. We will focus one game at a time but I am sure the squad will all have a part to play with such a busy time coming up in the next few weeks."
