Guinea are the last team into the Quarter-Finals against Ghana, after their ranking against Mali was decided in a hotel room: http://www.bbc.co.uk/sport/0/football/31047060
Cameroon letting the side down in Group D there, just one goal and it would have been a 4-way lot draw. CAF have reacted to the outrage (that of course has happened in spite of the rules being there from the start), by claiming they are looking into alternatives for 2017. Surely the best solution if the two teams are playing each other (as they were) is a penalty shoot-out once they know the result of the synchronised other match. The UEFA Euros has this rule in place for such a situation, as would have happened in the famous Turkey v Czech Republic match in 2008.
And if Ivory Coast v Cameroon was also 1-1, both matches could have continued to shootouts, both winners progressing and the lots coming into play to determine the order of the remaining tied teams.
Also to look forward to in the Quarter-Finals this weekend, favourites Algeria and Ivory Coast play, Tunisia face hosts Equatorial Guinea, and Congo play (DR) Congo. The last one will be an interesting one for the commentators to handle...
