Mamut began his career at the age of four with Club Las Malvinas, prior to his departure to Asociación Deportiva Anunciación de Fútbol Infantil (ADAFI) in 2013.[5] Three years later, Mamut headed to Gimnasia y Esgrima.[5] He signed his first professional contract on 27 January 2020; aged sixteen.[2][6] Mamut, who'd appear non-competitively in the intervening period, made the jump into senior football just over twelve months later on 19 February 2021, as he appeared on the bench for a Copa de la Liga Profesional match against Talleres.[7][8][9] His debut soon arrived, as he came on to replace Matías Miranda in stoppage time of a 3–0 win.[3]
Personal life
