Greene was speaking in the wake of Easter Monday's 2-0 win over North Ferriby United, although the Pilgrims remain the underdogs.
The United manager feels Guiseley will gain a positive result against Gloucester City on Saturday but maintains the Pilgrims will be ready to pounce on any slip-ups.
Greene reflected with pride on what has been an exhilarating and progressive season at The Jakemans Stadium.
