Banyana come into this clash looking to keep their title defence alive, while the Super Falcons continue to pursue their 10th championship.
Speaking at a post-match presser, Ellis says that at this point, past results don’t mean anything, as they look to take a bold approach into this encounter.
"I don't think past results mean anything, because it's a completely different tournament and a lot has happened since.
"They are the only country that has defended a WAFCON title, so we have to be at the top of our game to get over this massive hurdle.
"Our growth on the international stage and featuring in matches like this one once again stresses the need for a professional league," Ellis asserted.
Banyana will have to travel to Casablanca, where Nigeria have played most of their matches.
Ellis admits that the team is physically tired, but she has praised their mental coach for helping players to regain their mental strength.
"The celebration and togetherness after the Senegal game tells you that result has energized and reinvigorated the team.
"I think the mental coach has played a huge role. In 2022 she was valuable to the team, and it's been no different in this tournament."
Meanwhile, Nigeria coach Justin Madugu says they understand what rivalry means.
"We know what rivalry means, and we will not take anything for granted. We are fully equipped and ready for the semifinal."
