[1] Together with Henri Vascout and Étienne Jourde, he played a crucial role in the CA Vitry team that won back-to-back FCAF Championships in 1910 and 1911, which qualified the club to compete in the Trophée de France, reaching the 1910 final, which they lost 0–2 to Patronage Olier.
[1] At the end of 1911, Sollier was sent to Nancy to do his military service,[1][7] thus disappearing from the Vitry's line-ups, returning to the football world two years later, in 1913, but this time with a more modest club, Etoile du XIIIème.
[1] His fifth and last selection came against Hungary, which ended in yet another loss (3–0), and this time he was criticized by the journalists, who suggested that he had to give a gift to the FCAF's leaders, the Chailloux brothers (Henri and Louis).
[1] Mobilized at the outbreak of the First World War as a sergent in 103e Regiment d’infanterie,[8] Sollier was captured on 22 August 1914, in Ethé, in Wallonia, during the so-called Battle of the Frontiers.
[3][1] Like so many other French internationals from the start of the 20th century, Sollier was the victim of mistakes by historians, being initially given the first name André,[5][4][1] an error that persisted until the 21st century, even appearing in the Equipe de France de Football, l'Intégrale des 497 rencontres ("French Football Team, All 497 Matches"), a book published by the FFF in 1991.
