Moneys beat Paulsgrove 7-1 in the 2018/19 final and, following a pandemic-enforced display, retained the trophy by beating Baffins on penalties in the 2019/20 final in May 2021.
Now they take on Gosport Borough two tiers up at PMC Stadium in Baffins on Wednesday (7.45pm) in this season’s showpiece event.
With Fratton Park unavailable, the final was originally scheduled to take place on April 6 at Westleigh Park – only to be postponed due to PDFA staffing issues.
Neither club was unduly concerned about the delay, and at least now the final is taking place on Portsea Island.
Moneys have not played since their Wessex Premier campaign ended on April 16 with a 2-0 defeat at Stoneham. Gosport, however, have played twice since then, ending their Southern League season with a 2-1 victory at Yate last Saturday.
“If Gosport is at full strength we will be huge underdogs,” said Turnbull. “As a collective, we don’t mind. We have no problem being the underdogs.
At Portsmouth USA, Turnbull enjoyed huge success in cup matches against top-tier opponents. But never has any of his teams beaten a team two divisions higher in the pyramid.
“We know they will be strong, they will be physical. We will have to be resolved from the start.
“It’s the old cliché…we’ll have to play our best and they’ll have to have a day off to make it a level playing field.”
Regardless of the result, Turnbull is happy with his first season at Moneys.
“We had a board meeting the other day and they seemed relatively happy. I was told we exceeded expectations which was good.
“To finish in the top 10 (Moneys finished ninth), to get through to a cup final, another semi-final (the Russell Cotes Cup) and with your two most influential players (Steve Hutchings and James Franklyn) out for 40% of the season… that’s acceptable, I’m happy with that.
“We were beating (Wessex champions) Hamworthy (in the league), we drew 5-5 at (third) Shaftesbury in the cup and beat them in the league.
“The only team that fooled us was Horndean twice. They taught us a lesson at home (0-3 defeat) and shattered us 88 minutes at home before scoring twice (2-2 draw).
“If we can tighten up at the back (next season), I think we’ll be fine.”
Franklyn and Elliott Turnbull miss the cup final through injury, while Jack Chandler – impressive at right-back in recent weeks – and striker Evan Harris are level in the cup.
Moneys will be aiming for his fourth win at PSC, having claimed silverware by beating Baffins in 2013.
Gosport have won the most since the first edition of the tournament in 1987/88. The borough has lifted silverware six times, including four in a row between 2003/04 and 2006/07 inclusive.
Like Moneys, Hayling, Horndean and Hawks have both won the trophy three times.
The Hawks – with current Gosport boss Shaun Gale as Lee Bradbury’s assistant – triumphed in 2015, 2017 and 2018.
