Santiago Grella

Santiago Grella Raviolo made his first-team debut for Unión de Santa Fe on 10 October 2025, coming off the bench against Central Córdoba in a match his side lost 1-3. The appearance followed a long route through the club's youth system: born in Devoto, in Córdoba Province, he moved to Santa Fe and joined Unión's academy, progressing through every age group before featuring for the reserve side in the Torneo de Reserva from 2022.

By early 2025 he had been included in the first team's pre-season training camp in Uruguay. His first professional contract, running to December 2028, followed in December 2025.

Grella played one Liga Profesional match in 2025 and three reserve fixtures in the Copa Proyección, then added five Liga Profesional appearances in 2026 — four in the Apertura and one in the Clausura — plus a game in the Copa Argentina. In the Apertura he was on the pitch for 65 minutes, averaging a 6.2 rating, without a goal or an assist to his name in the top flight.

His clearest mark on the club's season came in the Copa Santa Fe, which Unión won in 2025. Grella started the semi-final against Atlético Rafaela, won on penalties 5-4, and was part of the squad for the final against Centenario, settled 3-2 in another shoot-out.
