County signed him in January 1892 but, after only making only four appearances, he was transferred to East Midlands rivals Nottingham Forest in 1894, where he was soon joined by his brother.
Illness and injury restricted his appearances in 1897–98 and he played no part in Forest's FA Cup success in which they defeated Forman's former club, Derby County in the final 3–1.
By the end of the following season (1898–99), he was restored to fitness and was selected for all three England matches in the 1899 British Home Championship, in all of which he played at outside right with his brother Frank at wing half.
He made his international debut in the match against Ireland, played at Roker Park, Sunderland on 2 March 1899 when he and Frank became the first brothers from the same professional club to represent England at the same time,[1] a record that stood until Manchester United's Gary and Phil Neville repeated the feat in 1996, nearly a century later.
[3] Forman retained his place for the next match against Wales, played at Ashton Gate, Bristol on 20 March when he scored the third goal in a 4–0 victory, with two from Bloomer.
