Américo Miguel Tesoriere, sometimes nicknamed Mérico (Buenos Aires, March 18, 1899 – December 30, 1977), was an Argentine football goalkeeper who spent most of his career in Boca Juniors. He is regarded as one of the first idols of the club, and as one of the best Argentine goalkeepers. 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, keeping his goal unbeaten in both competitions.
