Overview
- Boca slipped to third in Group D after Wednesday's 0-0 in Santiago between Universidad Católica and Cruzeiro, which left both on seven points to Boca's six with Barcelona SC on three.
- Boca hosts Cruzeiro on Tuesday, May 19, and then Universidad Católica on Thursday, May 28, with both matches at La Bombonera in Buenos Aires.
- Winning both home games would guarantee a last‑16 berth and first place in the group, which carries home‑field advantage in the round of 16.
- A draw against Cruzeiro followed by a win over Católica would also see Boca through, using head‑to‑head results as the tiebreaker if teams finish level on points.
- Boca could be eliminated next matchday if Cruzeiro win in Buenos Aires and Católica beat Barcelona SC in Chile, which would put both rivals out of reach with one game to play.
