A lone Caio goal was all that was needed for Al Wasl to win 3-2 on aggregate after a draw with rivals Al Nasr in the first leg, 2-2. The game came in the absence of Fabio Lima, who was sent off in the home leg.
However, the biggest talking point of the match came when Khaled Jalal of Al Nasr attempted to attack Ronaldo Mendes of Al Wasl at the end of the match, with officials and coaches preventing a scuffle from breaking out.
