Overview
- The 28-year-old joins on a one-year loan carrying a reported $500,000 fee, with an obligation to buy that activates if he reaches a defined playing-time threshold cited as 50%.
- Local reports indicate the clause would compel River to purchase 50% of his rights, with a path to acquire the remainder through additional payments.
- He is expected to link up with preseason in San Martín de los Andes and becomes River’s third 2026 reinforcement after Fausto Vera and Aníbal Moreno.
- Viña endured a severe right ACL and tibia injury in August 2024 and logged only about 10–12 official appearances in 2025 after a roughly nine-month recovery.
- Signed to cover the left flank after Milton Casco’s exit, he will compete with Marcos Acuña and can also serve as a central defender.
