Although the Blues would win just one more away match in the remainder of a disappointing season. Picture: Joe Pepler Photo: Joe Pepler
14. Pompey 3 Barnsley 2 (April 16, 2024)
Trailing 2-1 to Barnsley with seven minutes remaining, it appeared the promotion and title champagne would have to remain on ice a little longer. Then, as ever with John Mousinho's remarkable side, they rallied to find a way to win. Firstly substitute Colby Bishop levelled from the penalty spot, then Conor Shaughnessy headed home Marlon Pack's corner in the 89th minute to claim the League One crown in dramatic fashion.
