And they have not lost since round three, when last year's Aviva Premiership runners-up were pipped to the post by Gloucester Rugby at Kingsholm.
However, Jim Mallinder's side will have to forget about their domestic triumphs of late and focus on Europe, as reigning PRO12 champions Leinster come to town this weekend.
As well as the disappointment of last season's Aviva Premiership final, Saints missed out on a spot in the last eight of the Heineken Cup.
And second row Samu Manoa, the Aviva Premiership Rugby Player of the Month award for October, is braced for a huge battle to ensure that does not happen again.
"The Heineken Cup is just another level of rugby and the boys are looking forward to it," he said.
"The boys are excited when the Heineken Cup comes around and everybody has got to bring their A-game to the table.
"We will worry about Leinster when Leinster come. It is massive for the club and for us boys. We were upset about how it turned out last year.
"They have got a good squad and we have got a good squad too, so there is going to be a clash."
Saints lie second in Pool 1 after the opening two matches, which saw them slip to a narrow defeat at Castres Olympique before beating Welsh outfit Ospreys.
A win on Saturday would see Northampton move ahead of early leaders Leinster, before the Irish side return to Franklin's Gardens the following weekend.
Manoa, who was named Aviva Premiership Player of the Month for October, has been a driving force for Saints this year, but he believes there is still a lot left in the tank - personally and from a team perspective.
"There is a lot of stuff I can improve on but I am playing pretty well right now. I have just got to keep up with it," he added.
"Life is good and I am just taking it day by day. Every day is just another day in paradise."
