David, 77, played 272 times for the club in his 10-year career at Old Trafford, and has become the second of 19 players who will be honoured for their contribution to the club’s success following the medal presentation to David Gaskell in June.
Under English Football League rules at the time, Sadler did not qualify for a championship medal in the 1964/65 title-winning season, after falling short of the minimum 14 appearances then required.
The EFL has since lowered its criteria so that all players with five or more appearances for league-winning teams are entitled to recognition – and these new rules have been applied retrospectively to historic championships.
