last game of the 1973–74 season against Manchester United at Old Trafford, Law's 81st-minute back-heeled goal gave City a 1–0 lead but, thinking his goal might relegate United, Law did not celebrate the goal. Results of the day's other matches meant that United were relegated whatever their result, but Law did not know that at the time. A number of pitch invasions by United fans followed, and Law walked off the pitch with his head down as he was substituted. The pitch invasions forced the referee to abandon the game in the 85th minute. After a review, the Football League decided that the result should stand.
