Auguste Trousselier was a French footballer who played as a forward for CASG Paris and France (UIAFA) in the early 1910s.
He was the brother of André, a fellow footballer, and Louis, winner of the 1905 Tour de France.
Born in the 2nd arrondissement of Paris, Trousselier began his football career at his hometown club Racing Club de France in the early 1910s. On 30 April 1911, he started in the final of the 1911 USFSA Football Championship in Marseille, where one of his shots resulted in his side's opening goal in an eventual 2âÂÂ3 loss to Stade Helvétique de Marseille, a team made-up of English and Swiss emigrants; after the match, the French journalist Robert Desmarets wrote on L'Auto (the future L'ÃÂquipe) that "Trousselier was the most courageous of the attack".
On 20 February 1912, Trousselier was playing for CASG Paris when he earned his first (and only) unofficial cap for France (UIAFA), a friendly match against Catalonia, scoring twice to help his side to a 7âÂÂ0 victory; however, Desmarets expressed disappointed over his game, attributing it "to the emotion inherent in any international debut. He is thus one of the top scorers of UIAFA's France with two goals, alongside René Bagnol, Carlos Bacrot, and club teammate Albert Eloy.
In 1913, the USFSA selected Trousselier to play for the so-called Lions des Flandres, a regional scratch team representing Northern France, in a friendly match against the English Wanderers on 1 November, which ended in a 1âÂÂ4 loss.
During the First World War, Trousselier was taken prisoner.
