Panatuche Camara was brought on at half-time for the Reds to provide further attacking threat, and after a mazy run by Sanoh, who eventually rounded the keeper, he presented the opportunity for the substitute to slot home for 3-0.
It then went from bad to worse for Saltdean, as Crawley’s lead grew further thanks to a Smith penalty. Full-back Aryan Tajbakhsh played an inviting ball into the penalty area where United defender Matt Fleming fouled substitute Jordan Roberts.
The fans certainly got their money’s worth as they witnessed a true spectacle in the form of Smith’s wonder goal for Crawley’s fifth and the captains third.
The Reds skipper made a driving run down the right flank, cut inside onto his weaker left foot and curled an impressive strike into the top corner.
In the final moments Hall received his marching orders after picking up a second yellow card for a foul on Sanoh and that epitomised Saltdean’s evening.
Furthermore, in the dying moments of the match, Camara completes the scoring following a pinpoint cross from Sanoh, to send Crawley comfortably through to the Parafix Sussex Senior Challenge Cup Final.
