Club Atlético Unión and River Plate played out a goalless 0-0 draw in their Copa Argentina round of 32 match on August 29, 2025. The stalemate means the tie will be decided by a penalty shootout, as the knockout competition rules require a winner on the day. In a tense and tactical affair, both teams prioritized defensive solidity, leading to few clear-cut chances at either end. River Plate, as the top-flight giant, would have been expected to dominate, but Unión, likely from a lower division, organized themselves superbly to frustrate their illustrious opponents. The match saw half-chances and blocked shots, but neither goalkeeper was seriously tested over the ninety minutes. The draw is a fantastic result for Unión, who will head into the penalty shootout with confidence, while River Plate will be disappointed they could not find a breakthrough against a resilient defensive unit in a classic cup match scenario.
