Leeds reached an FA Cup semi-final for the first time in 39 years – but only via a penalty shootout after they blew a two-goal lead in stoppage time.
Thousands of West Ham fans left early as the clock ticked round to 90 minutes after goals from Ao Tanaka and Dominic Calvert-Lewin put Leeds 2-0 up.
But those who left prematurely missed a cast-iron cup classic, starting with an astonishing comeback as goals from Mateus Fernandes and Axel Disasi forced a 2-2 draw and extra time.
They also missed 20-year-old fourth-choice goalkeeper Finlay Herrick thrown on for his debut in the shootout after Alphonse Areola went down injured at the death.
Herrick saved the first spot-kick from Joel Piroe, but Leeds keeper Lucas Perri denied Jarrod Bowen and Pablo Felipe to send Leeds through 4-2 on penalties.
