In a shocking encounter, River Plate faced a severe defeat of 4-1 against Tigre, with key contributions from Tiago Serrago, David Romero, and Nacho Russo, who scored two goals each. River's single goal came from Lautaro Rivero at the end of the match, which saw them down to ten men due to Fausto Vera's expulsion. This loss not only marks a tough night for River but also positions Tigre at the top of their group in the Apertura 2026, while River loses their unbeaten streak, both in matches and goals conceded.

Post-match evaluations revealed discontent with River's performance, with players receiving low ratings from analysts. The goalkeeper, Santiago Beltrán, who had previously gone unscored against, was particularly criticized for his performance, allowing multiple goals that should have been preventable. Other players, such as Gonzalo Montiel and Lucas Martínez Quarta, also faced scrutiny, with their inability to contribute effectively in both defense and attack during the game.

This defeat raises critical questions about River Plate's tactics under their coach Marcelo Gallardo and their preparation going forward in the Apertura. As they struggle to regain their footing after losing their dual unbeaten tag, the need for a tactical rethink and early season adjustments become paramount if they hope to contend in the league effectively this year.
