Gilbery scored the goal of the match – and arguably the season – when he collected goalkeeper Steve Murad's throw-out and raced from just outside the Fortune penalty area past the whole Shirley Park team to net a wonder goal – an incredible goal to fit any standard of football.
Benfredj was also the scorer of Shirley's second.
Fortune boss Lee Fegan told JC Sport: "Last week we all stayed behind after the Faithfold game and discussed as a team what needed to be put right. I'm delighted that everyone took things onboard and responded so well.
"We fought for each other and played as a team rather than a disjoined unit and reaped the rewards. We thoroughly deserved the win.
"It was a great result but if I'm honest, we didn’t even play the sort of football we are capable of playing but the effort was spot on."

Shirley Park boss Dave Lusman told JC Sport: "We were shocking in parts yet will still should've had this game wrapped up by the end of the first half. To be fair, Fortune were up for it and did what they needed to do as our 10 men struggled with hangovers from the night before.
