For those who give a toss, the other players in more recent times have included:
Andy Cole, Terry Cooke, Andrei Kanchelskis, Brian Kidd, Sammy McIlroy, Billy Meredith, Peter Schmeichel and Carlos Tevez.
Law, who scored 171 goals in 309 domestic appearances for Manchester United between 1962 and 1973, had played for Manchester City before - in the early 60s - and returned to what was then Maine Road in 1973, after being given a free transfer by Manchester United manager Tommy Docherty.
Manchester City's last game of the 73/74 season was away at Old Trafford, a game Manchester United needed to win if they were to have any chance of avoiding relegation to the old Division Two.
In the 81st minute, Law scored what turned out to be the back-heeled winner. He refused to celebrate, was immediately substituted and retired from professional football at the end of that season.
Law was upset as he walked down the tunnel after his goal that day, convinced that his back-heel had relegated his old club. As it turned out, Manchester United would have been relegated whatever the result that day.
All's well that ends well, however, as Manchester United got promoted at the first attempt the following season, and Law was eventually appointed an official Manchester United ambassador in 2012.
