(CNN) "Pressure and I are like husband and wife," Gabon coach Jose Antonio Camacho once said. On today's showing, it looks as though the marriage is more likely to end in divorce than happily ever after. After Gabon's opening day draw with minnow Guinea-Bissau, anything other than a win against Burkina Faso would make qualification for the knockout stage unlikely. Despite a spirited second-half effort, Wednesday's 1-1 draw means the host nation will be watching the late match between Cameroon and Guinea-Bissau with a keen eye. With that must-win nature of the match in mind Gabon started brightly. A mistake in the Burkina Faso defense inside the opening 60 seconds allowed Andre Biyogo Poko space down the right, but he was eventually smothered by a wall of white shirts.Gabon 1-1 Burkina FasoCameroon 2-1 Guinea-Bissau
