Born in Madrid, Redondo came through the ranks at Argentinos Juniors, making his professional debut in 2022 and appearing in 49 official matches for the club. His performances earned him a move to MLS in February 2024, where he joined Lionel Messi, Sergio Busquets, and Luis Suárez.
However, following the arrival of Rodrigo De Paul, the strong form of Yannick Bright and the undroppable status of Busquets, Redondo saw his playing time dwindle.
