Atlético-MG has announced the signing of Tomás Pérez, who was developed at Newell's Old Boys and had been with Porto since the previous season. During his time with the Portuguese club, he made 13 appearances for the B team and was part of the Argentine U-20 team that finished as runner-up in the 2025 World Cup. The signing addresses a priority for Atlético after the club experienced difficulty securing a defensive midfielder, having had unsuccessful negotiations for targets like Matías Galarza, Lucas Torreira, and Fred.
