In May, Gustavo Mantuan's name was linked with a potential return to Corinthians. Amid a transfer ban that prevents Corinthians from registering new players, Mantuan stated that there was no concrete negotiation with the club. He said that this time there were no conversations and nothing came up for him, his agents, or his parents. Mantuan added that they saw the rumour gained attention but, concretely, there was nothing this time.

Gustavo Mantuan, a 24-year-old Brazilian right-back, confirmed that Corinthians made an inquiry for him during the last transfer window and explained that they knew a move would be very difficult. He stated that because Zenit had already made it clear they would not release him at that time, it was only a light inquiry. Mantuan, who has a contract with the Russian club until mid-2030, also mentioned that he is not planning a return to Brazil at the moment but would give Corinthians priority when he decides to return. Mantuan joined Zenit in July 2023. His current market value is €5.00m, according to Transfermarkt. In the 2025/2026 Premier Liga season, he has made 18 appearances, scoring 3 goals and providing 2 assists.
