An agreement was in place between Santos and Racing for an exchange involving Adonis Frías and Gastón Martirena, which consisted of a one-year loan for the players with an option to buy. According to ESPN, the exchange is now at risk of not happening because Atlas has entered the negotiation at a late stage and is attempting to persuade Frías to alter his decision.

Santos and Racing are negotiating the exchange of defender Adonis Frías for right-back Gastón Martirena. The discussions are for a one-season loan with an option to buy at the end of the term, according to ESPN. The clubs are optimistic about reaching an agreement in the coming days.

Racing has targeted Adonis Frías, a 28-year-old Argentinian defender from Santos, to strengthen its central defense, a position weakened by an injury to Marco Di Césare and the departure of Agustín García Basso. The player, who has been pursued by Boca on multiple occasions previously, has made 29 appearances this season, mostly as a starter, and scored twice against Bragantino and Coritiba FC. Frías, a product of Defensa y Justicia's youth system, joined his current club in September 2025 and has previously worked under Juan Pablo Vojvoda, a factor that could be significant in potential negotiations. Negotiations are anticipated to be difficult because his contract runs until December 31, 2028. His transfer value is approximately three million dollars, and the financial aspect will be a critical element in whether a transfer occurs.
