Saturday's late collapse against Southend United pinned Town to the foot of the Football League, with chairman David Cardoza revealing that that is despite an investment of £7m during his time in charge of the club.
Sixfields is the venue again next weekend with a home fixture against Barnet that Northampton simply must win if they are to keep in touch with the teams, Barnet included, who are above them in the table.
"They're all crucial. We've got games left to make sure we get out of the position we're in and I'm very confident that we will," said Boothroyd.
"The supporters are seeing a team that's always in a game and having a go.
"We're a club that's tidying up and making sure we're always fighting for our lives."
