Boca Juniors vs Union Santa Fe: Union Santa Fe to win

Form Guide — Last 5
Boca Juniors
Boca's last five league results (D‑W‑D‑W‑W) include a 1‑0 win over Lanus at home and a 3‑1 victory against Central Cordoba, showing they can finish games strongly. Those wins, especially the 3‑1 home result, indicate a capacity to convert chances, reinforcing the view that Union's higher xG could still outscore them.
Union Santa Fe
Union’s form (W‑W‑W‑L‑L) features a 4‑1 home win over Sarmiento Junin and a 3‑2 home win versus Instituto, highlighting a potent attack that can breach defenses even when conceding. The recent three‑goal outputs suggest they are capable of matching or exceeding Boca's home scoring rate.
Head-to-Head
In the last five meetings, three have ended 1‑1 and each side has a 1‑0 win, illustrating a balanced rivalry that still leans slightly toward Union’s recent away scoring edge.
