The final then loomed against a very game and ready Sutton United team and it was the London side who took an early lead when, after a mix up at the back, they were gifted with an open goal.
A crazy two minutes followed, however, which involved Sussex completely turning it around and taking a 2-1 lead. First the equaliser straight from kick-off which saw Partridge put it on a plate for Lambert, powering into the middle of the net from close range. A second goal then came moments later when Lambert struck a fearsome volley into the top corner.
Sussex really had grit in their teeth at this point and looked to thoroughly see out the game with a third and they wasted no time in doing so when, seven minutes later, Partridge lobbed the Sutton ‘keeper from close range.
The second-half saw Sutton give it their best efforts to get back into the game but failed to really test Troncone in the Sussex net.
Sussex came close to a fourth midway through the half when, after Lambert struck a free-kick into the wall; Partridge then followed up with a volley firing agonisingly close of the mark.
Nonetheless Sussex hung on to the two-goal advantage and emerge victorious in Middlesex!
Sussex: Alnutt, Dobson-Walker, Francis, Greaves-Lord, Lambert, Lomas, Moore, Partridge, Phipps, Rogers, Smith, Troncone, Webley, Wray.
