Egypt isn't evolving, they are kind stable and struggling to show their maximum performance while Cameroon gameplay is improving from a game to another without fluctuations.
It will shock you that Egypt will play in the finals and also take the trophy. You may not like their pattern of play and you think they are a struggling side but you have to know that they are playing to instruction to conserve energy. That is what matters. Not what the Nigerian team did by winning all their three group matches and then lost miserably to Tunisia.
Egypt will definitely be Cameroon's biggest task yet this tournament, and honestly I wouldn't write-off the Egyptians chances of making it to the finals, Cameroon look the better team, but they've really not been under any really pressure, while the Egyptian have played through all tournament long, and that might be in their favor in this fixture.
Cameroon vs Senegal is my expectations for the Finals btw.
This nation cup is some how difficult to predict who will move to the next round based on what I have observed in this tournament so far. Your expectation for Cameroon vs Senegal might be dash if care is not taking since anything is bound to happen. The Egyptians should not be completely roll out if take time to compare their get so far.
