## Cup

The final of the Cup was surprisingly between two minnows, SC Beira-Mar – who had just been relegated – beating SC Campomaiorense 1–0, after the precocious elimination of all stronger clubs, with FC Porto and S.L. Benfica being eliminated in the round of 32 and Sporting CP in the round of 64.
