Ian Sampson described his side's opening 20 minutes as 'probably the best they've played' this season and feels that confidence at Sixfields is sky-high as the business end of the season approaches.
The Cobblers now lie three points above 8th-placed Dagenham & Redbridge and only six points behind the automatic promotion places.
Tuesday night's action sees Accrington Stanley and Aldershot look to make the most of their games in hand before Sampson takes his men to struggling Lincoln City next Saturday.
