Juan, after being transferred to Southampton, is currently playing on loan at Goztepe in Turkey. The transfer to Southampton took place in 2024 as part of a financial compensation deal, following his previous association with São Paulo. However, the financial details of the transfer have come under legal scrutiny. His agent, Norberto Luís Zanelatto, has claimed that he was not informed about the specifics of the transaction, despite owning 5% of Juan's rights. As a result, Zanelatto has initiated legal proceedings against São Paulo to acquire this information. Meanwhile, Juan continues his career on loan at Goztepe.
