Joint manager Lee Canoville insisted Boston United can still make the Blue Square Bet North play-offs after a 2-1 win at Hinckley United.
Spencer Weir-Daley's double took Boston to within six points of the top five, with Lloyd Kerry scoring for Hinckley.
Canoville told BBC Lincolnshire: "It's a massive win, the boys grafted hard.
"I'm sure a lot of people would have written us off a few weeks ago but we believe the lads can do it and they're starting to believe it now."
He added: "Everyone can see the team is growing in confidence. We know where we want to be but we're still a little way off and there's a lot of work to do.
"It will be tough, there are a lot of hard games to come but we're going to do our best and if we can keep picking up three points and putting pressure on the teams above us we'll be absolutely delighted."
