Flying Eagles head coach Aliyu Zubairu has promised an improved performance from his players against South Africa.
Nigeria will take on the Amajita in a semi-final fixture at the 2025 Africa U-20 Cup of Nations in Ismailia on Thursday.
The Flying Eagles booked a date with South Africa after overcoming holders Senegal 3-1 on penalities in the quarter -final at the Suez Canal Stadium, Ismailia on Monday.
South Africa on the other hand needed extra-time to beat Democratic Republic of Congo in their last eight contest.
Zubairus side earned plaudits for their impressive performance against the Senegalese, and the gaffer said his players will raise the bar once again when they do battle with South Africa.
