Mauricio Martínez was loaned to Unión without any fee. The move was part of a broader strategy by Rosario Central, who sent eight players out on loan without charge during the transfer window. Martínez, alongside players like Ulises Ciccioli and Kevin Silva, was part of this group as Rosario Central focused on optimizing their squad under the new management of Ariel Holan. This decision reflects the club's approach to managing player development and financial resources.
