River decided to leave behind a 2025 to forget with an aggressive, non-stop transfer window. After finalizing the arrivals of Fausto Vera and Aníbal Moreno to strengthen the midfield, the board and the coaching staff moved forward decisively to cover another sensitive area of the team: the left-back position.
The difficulties in finalizing negotiations for Román Vega, Julio Soler, Elías Báez, and Alexandro Bernabei led Millonario to redirect the search. In that context, the name of Matías Viña emerged strongly, a player who belongs to Flamengo, for whom the Núñez club submitted a formal loan offer with a purchase option.
The response from the Brazilian club was positive and the talks progressed quickly. In recent hours, River, Flamengo, and the player's camp reached a verbal agreement that finally unlocked the deal.
One of the decisive factors in the negotiation was the player's desire, which was a determining factor. Viña pushed hard to wear La Banda's jersey and to take on a new challenge in his career. Thus, the recent Copa Libertadores champion released the defender so that he can join the squad coached by Marcelo Gallardo.
