Havant & Waterlooville recently combined and the former Southern League rivals have leaped up the football pyramid since doing so, but the gulf in class between the two sides was immediately obvious as they were swept aside by a hungry Pompey team.
Young Scot Marc Burchill was the star of the show netting a first half hat-trick with assists from Lee Bradbury and Courtney Pitt, completing the honour with a penalty after a fowl on Pitt.
The rout was completed with two Chris Clarke goals and another by Rowan Vine, but the star of the show was the goalkeeper.
Trialist Sergio Leite, who is rejecting offers from FC Porto and Boavista, made several fantastic saves and is poised to sign a contract to provide competition for Herald Wapennar and Shaka Hislop (and possibly even Yoshi) for the number one jersey.
Leite is only 23 and has been a fixture for Portugal in the under 18 and under 21 squads over the years, and looked to be an excellent goalkeeping prospect.
But despite the success of last night's game, the reserves with not have a repeat chance to impress at Bognor Regis Town on Saturday. The Rocks have cancelled the West Sussex showdown siting an unplayable pitch surface as the reason.
