With Ghana having made the knockout stage of the 2017 edition, the Starlets dream is well on course.
“We’ve got more than one objective here,” Ayiah, who scored twice in Ghana’s last game, told Fifa.com.
“We’ve achieved the first and now we’re going after the rest. We need to make it to the final and try and win the title.
“We set ourselves a few objectives after we qualified, the first of which was to finish first in our section.
“We’re going to be focused and calm as we go about achieving the rest of our goals. We have what it takes to do what we came here to do.”
To win the cup, Ghana must overcome familiar foes Niger in the Round of 16 on Wednesday.
The two sides have already met three times in 2017, all games going in favour of the Starlets.
“We think we’re going to perform well and win the game,” Ayiah said.
“We want to score and I think we’re capable of winning it before a shoot-out.
“We’ll be doing all we can to keep our run going. As a forward, it’s my job to score goals.
“And I’m happy when I do it, especially if my team wins and makes progress in the competition.”
But a 4-0 triumph over India in the last group game was enough to see the Starlets finish top of Group A to secure passage to the next stage.
