Américo Miguel Tesoriere, sometimes nicknamed Mérico[2][3] (Buenos Aires, March 18, 1899 – December 30, 1977), was an Argentine football goalkeeper who spent most of his career in Boca Juniors, where he became an early idol and remaining as a legend of the club.

[2][5][6] Tesoriere was the third goalkeeper in the history-of the Argentina national team after José Buruca Laforia and Carlos Wilson, winning two Copa América with the squad and keeping his goal unbeaten in both competitions.

Born in Barracas as Américo Miguel Tesoriero in 1899,[2] he "established" a club with his boyhood friends, "Coronel Brandsen", named after the street where they used to play football, just in front of a butcher shop.

Bucceli discovered Tesoriere while he was playing on a vacant land next to BA&ER rail tracks, just on Brandsen on Del Crucero streets, where the Boca Juniors stadium would start to be built in 1922.

Nicknamed La Gloria,[9][12] Tesoriere soon gained the attention of media and fans for his skills and good performances, being called up for the Argentina national team in 1920.

[2] At the end of the Argentina v. Uruguay match for the 1924 South American Championship, Tesoriere was carried aloft by the Uruguayan supporters as a recognition for his outstanding performance during the game.

[9] On 31 December 1927, Tesoriere played his last official match for Boca Juniors, when the squad beat San Lorenzo 2–1 at Estadio Gasómetro in the last round of the 1927 Primera División championship.

[9] The famous song "We have a goalkeeper who is a marvel himself; He stops penalty shots sitting on a chair" was composed by the Boca Juniors supporters in honor of Tesoriere.

[7] Tesoriere was very fond of poetry, having written several poems that were compiled by his son Eduardo and edited on the book Américo, el poeta del arco, published in 2017.
