O'Farrell's replacement was to be Scotland coach, Tommy Docherty. Docherty left the Scotland job and his first task at United was to keep the club in the top flight. He managed it once, but he was unable to pull it off again and the club was relegated in 1973–74. They bounced straight back up the following season, though, and in their first season back in the top flight, the team cruised to a third-place finish and yet another FA Cup final. The next year, they went one better, beating Liverpool in the final to claim his first and only trophy at Old Trafford. It was soon discovered, however, that Docherty was having an affair with the wife of the club's physiotherapist, and he was immediately fired, replaced by Queens Park Rangers' manager Dave Sexton.
