Cristopher Núñez left Lamia under controversial circumstances, being accused by the club of a lack of professionalism, which his wife Valeria claimed were lies. He immediately found a new team, returning to Cartaginés in Costa Rica, where he began his football career. Cartaginés announced Núñez as their second official reinforcement for the upcoming tournament.

Christopher Núñez is on the verge of ending his contract with Lamia, with only minor details left to finalize. Cartaginés has expressed interest in acquiring Núñez. He has been left out of Lamia's squad for the upcoming match against AEK, indicating that his departure from the club is imminent. Furthermore, Núñez has already received formal offers, including a proposal for a three-year contract from Saprissa, and there is interest from other Costa Rican clubs such as Alajuelense and Herediano. Although there is some speculation about possible moves within Greece or to Cyprus, Núñez is mainly associated with a potential return to his home country.
