With superstar No. 10 Lionel Messi left to a late substitute appearance, the Herons fell behind early when Otavio opened the score for the Arab Club Cup champions with a third-minute goal.
Things quickly unraveled from there, as Miami conceded twice more in quick succession to Talisca (10′) and Aymeric Laporte (12′) – with the latter scoring a long-range effort from his own half after catching goalkeeper Drake Callender off his line.
New signing Luis Suárez threatened to pull one back in the second half, but Miami’s comeback never materialized. Talisca struck twice more in the final 45 minutes, while Maran also got his name on the scoreboard with a late header.
