The pattern of the game continued in the early stages of the second-half, with Sussex probing away without success. Substitutions were made by both sides, with Tyrese Mthunzi making a positive impact with a 20-yard shot on the hour mark, which riffled just over.
The game changed following a switch by Sussex Assistant Manager, Ian Browne. Essah Jennah, who had been playing in central midfield, was moved to become the central striker, alongside young under-18s debutant Jake Hutchinson. This also freed up Josh Gould to have a more creative role.
Accordingly, Gould picked up the ball in his favourite left channel, and had a cross shot across the box, the Hertfordshire goalkeeper parried and Jennah was on hand to slide it in at the back post to equalise.
As it stood, Sussex had the point they needed to win the Group, but they wanted the win. Minutes later, Gould and Jennah almost combined identically to score again but Jennah couldn’t quite make contact this time.
Gould was now running the game, and thriving in his new role as captain. Towards the latter stages of the match he fought off a defender and smashed a shot over the bar.
With just six minutes remaining, Sussex landed the killer blow. Gould again had the ball in the left channel, and swerved a pin-point cross into the box where Hutchinson met it first time and scored with the instincts of a true goal scorer making it 3-2 to Sussex.
Sussex withstood late pressure from Hertfordshire, with Tolo Shawumni heading into the hands of Glover, and May Hutchinson shooting straight at Glover who gathered comfortably.
Sussex held on, to secure the win and cement their place at the top of Group B. It was a great game of football, with a dramatic finish. The game changed in the second-half with the tactical switch from the Sussex management team, and Sussex always looked like winning after that...
