The basement battle was evenly-poised until United had midfielder Keiron Elliott sent off after half-time — and then lost the services of key defender Lewis Sturman to a groin injury.

Guiseley took complete control thereafter and quickfire goals from Ben Whitfield, Redmond Lee, Luke Robinson and Ashley Tatler put the match well beyond United’s reach.
