Guinea-Bissau offered little going forward with their best opportunities falling to Judilson Gomes and Juary Soares, who both fired over.

Banana opened the scoring after 66 minutes when he got on the end of a corner from Ekambi to head low past Mendes into the net.

It was 2-0 just three minutes later when a defensive mix-up in the Guniea-Bissau box saw an attempted clearance hit Sory Mane and the ball then dropped for Bahoken to calmly slot home.
