Cameroon are making their 18th appearance in the tournament. They have won it four times (1984, 1988, 2000, 2002), only Egypt have been more successful (7 trophies).
Meanwhile, Guinea-Bissau are the only team making their debut in the African Cup of Nations this year.
Only two of the last eight teams to make their African Cup of Nations debut have progressed to the knockout stages (Equatorial Guinea in 2012, Cape Verde in 2013).
Cameroon were victorious in their only two previous encounters with Guinea-Bissau, winning 1-0 in both of their 2013 AFCON qualifiers.
Guinea-Bissau boss Baciro Candé is making his first appearance as manager in the tournament. It’s the same situation for Cameroon boss Hugo Broos.
Cameroon are currently enduring a six-game winless run in the African Cup of Nations (D4 L2) whilst Guinea-Bissau’s first ever appearance in the competition ended in a 1-1 draw against Gabon.
Cameroon have gone nine AFCON matches without a clean sheet and have also been unable to score more than once across their last five games in the competition.
Three of Cameroon’s last four goals in the African Cup of Nations have come from a set-piece situation whilst Guinea Bissau’s only goal to date in this tournament came from a free-kick.
Benjamin Moukandjo has scored Cameroon’s last two goals in the African Cup of Nations; both coming in the first-half (vs Guinea in 2015 & Burkina Faso in 2017).
Juary Soares’s 90th minute equaliser for Guinea-Bissau came from his only shot in the game against Gabon; the last two goals recorded by his country have come in the 90th minute (Toni Silva v Zambia, June 2016).
