The shopping centre side are the first team from the town to win the competition since Stocklake, a previous incarnation of Southern League side Aylesbury FC, won it in 1995.
The landmark title was the first of two trophies brought back to Aylesbury at the weekend as Two Touch – featuring a number of players from Hale Leys – were also victorious in their own county cup final (see page 114).
Not only was it a landmark trophy for the town, but also Hale Leys manager Paul Alleyne in his maiden season as a boss.
Alleyne, a prolific forward in his playing days – most notably at Aston Clinton where he is the club’s record scorer – saw his side go 1-0 down to an unfortunate own goal early in the second half of a tight affair.
Hale Leys stopper Ashley Jenkins made a game defining save to keep Alleyne’s men in the match but it looked like it could be in vain until Daniel Parsons pounced two minutes from the end.
The talented and versatile player is a essential member of the Hale Leys team and showed why with a stunning piece of skill to control the ball and then slot home to force extra-time.
The first half of extra-time proved predictably cagey as the energy drained from both sets of players.
Hale Leys pulled themselves together, though, and Tom Brindley held the ball up well to bring Jason Castello into play.
That was to prove the decisive moment as he smashed a shot into the Aldermaston net to bring the cup home and leave boss Alleyne brimming with pride.
He said: “I am so proud of everyone. They showed what we were capable of on the pitch and it was hard to pick out one player but had to be Jason Castello – what a way to win the cup!
“Credit to Aldermaston they made us work for it. It was a valliant effort from them and they were very worthy finalists.”
Assistant manager Roni Joe, a former Aylesbury United striker, added: “It was a huge win! The boys gave everything. I hope this is the first of many trophies for this great club.
“It’s been nearly 20 years since this was brought back to our town and I’m pleased that it came back with us.”
Hale Leys co-ordinator John Watson said: “I would like to congratulate and thank everyone involved with the club for the support which was overwhelming. I would also like to congratulate our players who won the Sunday county cup as well, what a weekend for Aylesbury football!”
