Wrexham director Shaun Harvey says the club's season can be considered a success whatever happens this weekend.
The Red Dragons occupy the last remaining play-off berth ahead of the final round of matches, where they host fourth-placed Middlesbrough on Saturday.
While Harvey claims if they do achieve a fourth promotion in a row it would be the "greatest sports story ever", he would not want missing out on a play-off place to be deemed a failure.
"The time is now. We've got one game to go of the league season," Harvey said.
"To use [Manchester United managerial legend] Alex Ferguson's favourite phrase, it definitely is 'squeaky bum time'. Will we make it or won't we make it? Well, there's a story to be written either way.
"Because whatever happens, we've gone from being a non-league team to the best team in Wales by virtue of league position.
"We've finished in our highest league position ever and the women's team have won the [Adran Premier] league and will compete in the Champions League."
