Despite the scoreline, many positives can be taken from the game against a full strength SCFL Division One side.
Former Under 18 'keeper George Jackson made his first team debut, whilst there were also starts for Ben Farrant, Patryk Miszkiewcz and Howard Sturgeon, all of whom are still eligible to play Under 18 football.
The returning Luke Denton took his place alongside Miszkiewcz as Simon Rowland shuffled his pack with one eye on the FA Vase tie against Phoenix Sports.
A fairly even first quarter was brought to life when an angled through ball from Sturgeon found Jack Divall clean through, but Divall was brought down by onrushing Newhaven 'keeper Jake Buss.
After a consultation with the assistant referee, the match official only produced a yellow card for the Newhaven 'keeper, much to the surprise of everybody within Fort Road.
Five minutes later, United found themselves behind when Lee Robinson found space on the right wing to play in James Rhodes who placed the ball past Jackson from 18 yards out.
Newhaven doubled their advantage as half-time approach when Robinson slotted a low effort past Jackson after making space behind the United defence.
The second half saw two more products of the successful Under 18 team make their first team debuts as Charlie Osborne and Jake Modestou entered the action.
Newhaven put the game past their plucky opponents on 66 minutes when one time United forward Tyler Goatcher hit a thunderous effort past Jackson.
Osborne brought a more direct approach to the United side after his introduction and showed maturity beyond his years when he cut in from the left and saw a curling effort goes inches wide.
Osborne was again involved in United's best chance of the evening as he combined with Jason Taylor to tee up Linton Rogers who saw his fierce drive turned over by Buss at the near post.
The performance of the younger players in the United side will have no doubt given Rowland some food for thought as the future of Eastbourne United AFC looks brighter than ever.
