I haven't watched the South African women in the Women's African Cup of Nations, so I don't know if they will be a difficult opponent for the Nigerian Super Falcons if they meet in the Women's African Cup of Nations. With the way the Nigerian Super Falcons played in the group stage of the Women's African Cup of Nations and the way they dominated the Copper Queens of Zambia yesterday, I believe if they play against the South African women, they will beat them.
If you have watched some other African women who has played very nice that's example of how the South African women played and I have watched them play with the Nigeria women on the CAF women qualification twice if we should count it and they had a very strong players on the forward line plus the center midfield but the first was won by the Nigerian women one to nail while they returned back again to play a goal less draw so actually they are very important and they have the squad to carry them to the semi finals or even finals because if the Nigerian women can reach there definitely the can.
I had the opportunity to watch the South African women play against the Senegalese women in the Women's African Cup of Nations, and from the few minutes I watched them play, they dominated the Senegalese women, so I agree with you that the South African women are strong and they will be a difficult opponent for the Nigerian Super Falcons today.
