He was one of the 'Lisbon Lions' who won the 1967 European Cup final against Inter Milan, a final in which Gemmell scored an equalising goal with a shot from outside the penalty area. Ironically, Gemmell should not have been in position to score the goal, as he had ignored team orders for one full-back to stay in defence at all times; the right back Jim Craig had already ventured forward, and it was he who played the square ball for Gemmell to shoot, with both advancing on the Inter box.
