Aldosivi vs San Miguel Prediction & Betting Tips (17 February)

Aldosivi’s clash with San Miguel in the 2026 Copa Argentina round of 64 arrives at a moment when the national cup has already produced its first shocks and headlines. The 14th edition of the tournament kicked off in mid-January with 64 teams chasing a rare piece of silverware, and Midland’s penalty shootout upset of Argentinos Juniors has underlined how fragile favourites can be in this format. Aldosivi, drawn at a neutral venue but listed as the home side, are expected to control more of the ball, yet San Miguel’s hunger to prove themselves on a bigger stage gives this tie a tense, unpredictable edge that goes beyond simple league hierarchies.

For Aldosivi, this Copa Argentina opener comes on the back of a demanding start to the year in domestic competition. They have already visited Gimnasia La Plata in early February and recently hosted Defensa y Justicia in a tight encounter that finished goalless, adding to a run that also includes strong results late last year against San Martín de San Juan and Banfield. Those league outings, plus the upcoming trip to face Tigre, show a side that can alternate between cautious control and sudden attacking bursts. The earlier meeting away to Gimnasia LP highlighted how Aldosivi are becoming more comfortable defending deeper spells without losing their structure, something that could be crucial in a knockout setting.

San Miguel arrive from the lower divisions with less spotlight but plenty of competitive rhythm, having faced a series of rugged opponents in recent months. Their calendar has included trips such as the visit to Gimnasia Jujuy and a demanding away date against Los Andes, fixtures that tend to sharpen a team’s defensive instincts and collective resilience. While detailed scorelines from those league matches matter less than the experience gained, San Miguel’s players are used to tight pitches, direct football, and managing long spells without the ball. Translating that mentality into a one-off Copa Argentina tie, where concentration and set pieces often decide everything, could help them narrow the gap in quality and turn this into a genuine contest rather than a formality.

All signs point toward a tactical battle defined more by caution than chaos, with Aldosivi likely to probe patiently and San Miguel content to compress space, delay transitions, and lean on their physical duels. Recent performances suggest Aldosivi are comfortable in controlled, low-scoring environments, while San Miguel’s league background has conditioned them to scrap for every second ball and protect their penalty area with numbers. With neither side wanting to become the next big upset headline so early in the competition, a stalemate feels entirely plausible, and our prediction settles on a 0 : 0 correct score as the most realistic outcome over the ninety minu
