Overview
- River officially presented Viña as a new signing, with the defender posing alongside president Stéfano Di Carlo and senior club officials after completing his medical.
- The 27–28-year-old joins on loan from Flamengo through December 2026, with the club communicating a buy clause in the agreement.
- Local reporting cites a loan fee near US$500,000 and a US$5 million purchase obligation, figures that have been reported but not uniformly confirmed.
- Having joined preseason in San Martín de los Andes, Viña could make his first minutes in Uruguay friendlies against Millonarios on January 11 or Peñarol on January 17.
- His arrival strengthens the left side of defense as Marcos Acuña manages a persistent big-toe issue, and he arrives with major honors including multiple Copa Libertadores and Roma’s UEFA Conference League title.
