According to reports from various sources, Atlas was interested in Guillermo Martínez. The 30-year-old Mexican Pumas forward was not in the squad for the opening match of the Clausura 2026. Despite being the starting striker last semester, Martínez was not on the bench, which led to speculation about his departure. However, it was clarified that his absence was due to not being fully physically fit, as he did not train with the rest of the team during the last week. The absence was not related to the transfer rumors. The striker has 8 caps and 2 goals for Mexico, and scored 4 goals in 11 appearances in the Liga MX Apertura last season. He joined Pumas in January 2024 and his current contract runs until the end of 2026. His market value is €1.80m, according to Transfermarkt.
