According to TYC, upon returning to practice at Atlético Tucumán, Guillermo Acosta was informed that he would not be part of the sports project for the new season, despite having one more year on his contract. The departure is related to discord between players and executives during the final matches of the Torneo Clausura. This situation affected the relationship, and the differences created a significant distance in the player-executive bond, with unresolved issues leading to Acosta's exclusion.

According to TYC, it is not certain that Guillermo Acosta will continue at Atlético Tucumán due to some disagreements with club directors in recent months. These differences have created a significant distance in the relationship, and there are unresolved issues that could potentially result in Acosta leaving. It is reported that Hugo Colace hopes to have the midfielder in the squad and is said to have expressed this to the player, but the final decision will be made by president Mario Leito and the Board of Directors. A meeting between Acosta, club directors, and the Technical Secretariat is expected before training resumes to attempt to restore dialogue or determine the footballer's future.

Argentine central midfielder Guillermo Acosta, 37, has a contract until December 2026, but it is not certain if he will continue, which will depend on discussions he will have with the directors in the coming days. The midfielder joined his current club in July 2019. According to Transfermarkt, he has a current market value of €200k.
