Cameroon vs Guinea-Bissau Match Preview. Cameroon have been very solid in 2019 and only saw their three-match winning streak ended by Mali in a 1-1 draw earlier this month, as they fell behind early on but Toko Ekambi netted a late first-half equalizer. They now meet Guinea-Bissau as they open competition in AFCON Group F, hoping to bounce despite losing the hosting rights and prove their worth early in Egypt.
