The 2015-16 campaign was an extraordinary story of resurgence for Barnsley, delivering double Wembley silverware and a dramatic promotion. The Tykes performed a spectacular turnaround, climbing from bottom of League One in December to clinch a 6th-place finish and a play-off spot. Leading the charge was the prolific Sam Winnall, whose 21 goals proved crucial. Their season culminated in two triumphs at Wembley: first, winning the EFL Trophy against Oxford United, and then securing promotion to the Championship with a dominant 3-1 victory over Millwall in the Play-off Final. It was a historic year that marked the club's hard-fought return to the second tier.
