As stated above, Law played and scored in the Texaco Cup (as the Anglo-Scottish Cup became known after one of football's early sponsorship naming deals) at Sheffield United on Tuesday, 6 August 1974. The next Saturday, he played in the 2-1 win at home to Oldham in the same competition and was replaced by sub Barney Daniels. City won 2-1 with goals from Francis Lee and Dennis Tueart, with the game being the last City appearance of both Lee and Law.
Law quit when, after the Oldham game but before the season opener at home to West Ham, Tony Book decided to sell Franny and sign Asa Hartford, switching to a 4-3-3 system rather than continuing to play four up front. One of the four remaining senior forwards - Law, Mike Summerbee, Rodney Marsh and Tueart - was going to have to make way and Book made clear that Law would be the odd man out. The Scot didn't fancy playing in the reserves and thought any transfer he got at that stage of his career would probably involve stepping down a division or two, so he decided to retire.
