The match, which was a repeat of the 2012 finals third place match, saw Ghana exact revenge after losing 2-0 for the bronze medal.

Ghana goalkeeper Fatau Dauda came out from his line to clear a ball but slipped in the process and had to handle it to deny Keita from scoring.
Referee Doue Noumandiez booked the glove man and awarded a free-kick which was cleverly taken.

Mubarak Wakaso also attempted to catch Mali goalkeeper Samasa Mamadou with a surprise shot from 25 yards but that went off target.
