Maurice Dubly

[4] In 1892, the 16-year-old Dubly, together with his younger brother Léon and a few other teenage friends of their age, formed a sports group called "French-Club de Roubaix-Tourcoing", which played association football and "Foot-Rugby".

[5] On 2 April 1895, after three years of playing this sport in informal meetings, either on a field located near the Croix-Wasquehal station or later on a meadow belonging to the Binet farm, this group finally decided to take a step further and officially established the club under the name "Racing-Club Roubaisien", doing so in a meeting held at the Brasserie "La Terrasse", rue de la Gare (currently avenue Jean-Baptiste Lebas) in Roubaix, and Maurice was chosen as team leader for the club's running section.

[2][8] In the 1901 final of the USFSA North Championship against Iris Club lillois, Dubly fractured his jaw in two places because of an unfortunate kick from an opponent, so he had to be carried off the field, bandaged in the locker room, and his friends then offered to accompany him home, but he instead decided to return to the field, and held on until the end, despite both the terrible pain and the pleas of his teammates who wanted to see him leave his post.

In the preview of the 1903 final, the journalists of the French newspaper L'Auto (the future L'Équipe) described the 27-year-old Maurice as "another old face, the true "pillar" of the whole team, the pivot of all combinations; plays admirably with his right foot as well as with his left; possesses to a rare degree of perfection the art of stopping the dribblings and charges of the opposing forwards".

[10] In the 1904 final, he started in a 4–2 win over United Sports Club [fr]; this was the retirement match of captain Léon, who was set to get married within two weeks.
