As it stands right now in the tournament, I believe the cup is up for grabs with the exit of egypt, cameroun and Morocco former powerhouses of African football, though we still have nigeria and Algeria. Funny enough, teams like Madagascar previously unheard of are swelling in confidence and may create upsets. So be careful with your bets.
I believe its a very good opportunity for Nigeria as it is now, Egypt has been their threat and now that they are out of the game I think I can now confidently place my bet without fear for Nigeria without fear although its still quite risky because no one expected Egypt to be knocked out the way they did, that means anything can still happen but for now, I would stick with Nigeria.
If the game does not work in favor of Nigeria, then its definitely Algeria, Madagascar has no chance of winning at all, I believe that definitely the Cup is for Nigeria this year but lets just keep our fingers crossed and see how it plays meanwhile any bet placed now is at the players risk.
