Charlie Goode enjoyed the win at Cheltenham Town last Monday, but says that will count for very little if the Cobblers don't beat Exeter City in the play off final at Wembley on Monday.
"Last Monday was a special night," said the skipper.
"We believed we could do it and we went there and delivered but that has gone now and we have got a really big game ahead of us. That is where our focus is now.
"You saw the spirit we had last week. We are a close group, we all get on well on and off the pitch and we all work together and support each other.
"Last week means nothing if we don't get the job done on Monday. We have trained well and we are ready.
"We have a lot of experience in the squad. I think that is massive and that will be a big help to us.
"The real shame is that the fans won't be with us. We can feel their support and we are glad we put on a show for them at Cheltenham. We want to give them one more day to remember this season.
"Ever since I came here the fans have really taken to me. The reason I came here was to try and get promoted, we have a chance to try and do that and we will be giving it everything to try and make sure that happens on Monday."
