Player-manager Edgar Davids is preparing himself for another battle after Barnet boosted their survival chances with a dramatic late 1-0 win over Wycombe in the last-ever game at Underhill.
Striker Jake Hyde netted the winner from a Luke Gambin cross in the 81st minute before Graham Stack saved Joel Grant's penalty as Barnet brought to a close 106 years of playing at the famous old ground.
Davids wants the fighting qualities shown by his players to grind out the win against the Chairboys to be displayed again when they travel to Northampton..
"We created enough chances to win the game but we had to really battle to get it," he said. "We came in with a mission and we started with our foot on the gas.
"We really went for it from the first minute right up until the last minute. Wycombe couldn't deal with our pressure - we were pushing right up inside their half.
"If you believe from the first minute to the last that you will win, most of the time you will get that chance. And with Jake, if you miss a lot chances, the laws of football suggest that you will eventually be able to score.
"Conceding that penalty at the end sums up the season for us. Every game we play there is an error and we just keep doing it.
"Northampton also play very directly and they have two very good strikers so it will be another tough battle for us."
Meanwhile, Wycombe boss Gareth Ainsworth, whose side are assured of League Two football next season, insisted if Grant had converted from the spot it would have been harsh on Barnet.
"We didn't deserve to get a draw from the game. That was probably the worst we've played since I've been in charge, I think the occasion got to a few," said Ainsworth.
