Iran dominated a friendly international against Costa Rica on 31 March, securing a commanding 5–0 victory in a one-sided encounter. Playing in a 5–4–1 formation, the hosts overwhelmed their visitors, who lined up in a 4–3–3 setup but offered minimal resistance throughout. The absence of detailed shot data and expected goals figures limits deeper tactical analysis, yet the scoreline alone underscores Iran's superiority in what proved a straightforward warm-up fixture. Costa Rica failed to register a single shot on target, reflecting their inability to create meaningful attacking opportunities against Iran's defensive structure. The result represents a significant confidence boost for Iran ahead of upcoming competitive fixtures, while Costa Rica will need to reassess their approach in future matches.
