Victor Osimhen scored twice as the Flying Eagles continued their winning streak with a 4-1 drubbing of Ace Academy of Kaduna in a test game on Saturday.
Kelechi Nwakali also scored from the penalty spot and Samuel Chukwueze equally hit target.
The Flying Eagles were tentative against a very spirited Ace Academy at the start of the game, but the gulf in class later showed when coach Emmanuel Amuneke brought in his first-team stars.
The Nigeria U20s have already beaten Sia-1 Academy 4-1 and Dabo Babes of Kano 6-0 in other test games.
They are preparing for an U20 AFCON qualifier against Burundi next month.
