Newbould's Derby reached the FA Cup final in 1903,[5] but lost 6–0 to Bury at Crystal Palace.
In 1906, financial pressures led Derby's directors to sell England international Steve Bloomer to Middlesbrough.
Newbould disagreed with the decision, and left the club at the end of the season to take up the managerial position at Manchester City.
Over the course of the season Newbould's City gradually recovered, winning the first top-flight Manchester derby 3–0, but only finished two places above the relegation zone.
After leaving City he had a brief spell as a coach at Copenhagen's Akademisk Boldklub before becoming secretary of the Players' Union in 1913, a position he held until his death in 1928.
