Overview

• Kickoff is set for 21:30 (Brasília) at the Maracanã, where Fluminense must win by two to advance or by one to take the tie to penalties.
• Coach Renato Gaúcho urged fans to fill the stadium and rested regulars in league play to prioritize the continental clash.
• Lucho Acosta is a candidate to start as Nonato is doubtful with a right‑foot issue, and Samuel Xavier could return to the squad after injury.
• Lanús arrives confident after the 1-0 home win, with Mauricio Pellegrino likely to keep the core XI and Marcelino Moreno as the main threat.
• Recent form at home bolsters Fluminense’s belief, with an extended unbeaten run in knockouts and a 12-game continental streak as hosts, while a pre-match plaque mix-up saw Lanús use another club’s crest before deleting the post.
