Atlético Tucumán took the Tomás Cuello case to FIFA and demands the payment of $850,000 that, according to the claim, Athletico Paranaense still owes for the operation that was closed in 2022. The decision has been cooking for some time, with internal conversations and legal analysis. The central point is concrete and in dollars. Atlético sold 50% of Cuello's pass in 2022 for $2.5 million and today claims a part that, according to the Tucumán position, is still unpaid. And the context adds pressure since Athletico Paranaense, in addition, has already transferred the Tucumán player to Atlético Mineiro for $3 million. So the Brazilian club must pay the pending debt. The directors of Atlético initiated the corresponding work for FIFA to take a position and dictate a sentence against the Brazilian club. In that framework, the possibility of FIFA urging the Paulista club under warning of subsequent sanctions was also mentioned. Behind this movement is a reality that Atlético has already publicly exposed months ago, and it is that the club needs to collect credits that are not arriving today. In October 2025, President Mario Leito spoke of a financial situation rather than an economic one, and explained that there were important income that could not be materialized. Among those points, he marked two specific cases: the money for Cuello in Brazil and the pass of Ignacio Maestro Puch in Independiente. Cuello's story, in addition, has its own journey. The player debuted very young in Atlético's First Division and had a stint with the Sub 17 and Sub 20 teams. His path took him first to Brazil, where he was on loan at Red Bull Bragantino and then was sold to Athletico Paranaense for around $2.5 million plus variables. The Brazilian club, later, transferred him to Atlético Mineiro for $3 million. But the claim to FIFA appears as a tool to try to cut a wait that has become long. And the Argentine club expects a resolution that will allow it to recover a key income. So the situation is complicated and the club needs a quick solution.
