Senegal did not show too much urgency at the start of the match, having already qualified for the knockout stage, and it was little surprise when the first half ended goalless.
Sadio Mane had a golden opportunity to break the deadlock just 11 minutes into the second half as he intercepted the ball from a Guinea defender and found himself one-on-one with Ibrahim Kone. The winger went past the goalkeeper but due to a heavy touch, failed to keep the final shot on target.
In the 61st minute, the Lions of Teranga finally opened the scoring when Abdoulaye Seck headed the ball into the goal from Krepin Diatta's inch-perfect free-kick.
Second-half substitute Iliman Ndiaye sealed the fate of the game in stoppage time as he scored following a pass from Mane to maintain his team's 100% win record in the group stage.
