Inter Miami was set to face Botafogo in Philadelphia after Luis Suarez scored a sublime goal to put The Herons up 2-0 on Brazilian giants Palmeiras.
What followed was a stunning collapse which will see them reach the knockout stages - but just barely as the finale of Group A featured two stunning results.
Inter Miami gave up two late goals to the Alviverde to draw 2-2 and let slip the chance to win Group A.
Now, that disaster will set up one of the most exciting matchups in the Round of 16: Messi, traveling to Atlanta, to take on his former club Paris Saint-Germain.
Briefly, with the score even in the late stages of the match and Palmeiras on the front foot, there was fear that Miami could be eliminated and Egyptian side Al-Ahly could take their place.
However, with the game going final as a draw, that hope for The Red Giant died out. Credit to them and opponents Porto, who played an enthralling 4-4 draw in New Jersey deserving of knockout spots for both sides.
