[5] In the stadium where his father Valentino played his last match,[6] Sandro Mazzola opened the scoring for Inter with a 7th-minute penalty after Jim Craig had brought down Renato Cappellini.
Celtic had two shots off the crossbar, and 39 other attempts on goal, 13 of which were saved by Italian goalkeeper Giuliano Sarti, seven were blocked or deflected, and 19 were off-target.
Craig made amends for his penalty mistake on 63 minutes, when he laid off the ball for Tommy Gemmell to fire home for the Celtic equaliser.
With 83 minutes on the clock, Gemmell was allowed space, and he played the ball to Bobby Murdoch, whose long-range shot was deflected by Stevie Chalmers past Sarti into the net.
The other members of the squad who played in Europe during that season were Charlie Gallagher, John Hughes, Joe McBride and Willie O'Neill.
