James Ernest Mangnall (4 January 1866 13 January 1932) was an English football manager who started his career with Burnley and managed Manchester United between 1903-1912 and then went on to manage Manchester City from 1912-1924, and is the only man to date to have managed both clubs. Born in Bolton, Lancashire, Mangnall played amateur football as a goalkeeper and was a director at Bolton Wanderers. He started his career in football management with Burnley in March 1900, when he was hired as the club's second official manager following the departure of Harry Bradshaw almost a year earlier.
