Matías Viña, a 28-year-old Uruguayan international who is looking to leave Flamengo, is a target for both Beşiktaş of Turkey and River Plate. The player reportedly gives preference to a move to the Argentine club, with talks for the transfer currently in progress. The parties are optimistic that an agreement can be reached. The left-back has shown little enthusiasm about the approaches from other clubs during the negotiation. Viña, who has 43 caps for his country, joined Flamengo in January 2024 from AS Roma for a reported €8.1 million and his contract is valid until the end of 2028. In December 2025, reports indicated Spartak Moskva had two bids of €3 million and €4 million rejected, with Flamengo's asking price set at €6 million. His current market value is €4.00m, according to Transfermarkt.
