Orji Okonkwo’s brace plus Samuel Chukwueze and Victor Oshimen strikes helped Emmanuel Amuneke’s lads overcome the Olympics team despite strikes from Godwin Saviour, Etebo Oghenekaro and Shehu Abdullahi.
Orji Okonkwo handed the Flying Eagles side the lead in the 10th minutes before Saviour leveled up in the 27th minute.
Okonkwo recovered the lead for the U20 side nine minutes later and Chukwueze made it 3-1 five minutes to half time break.
In the second half, Oghenekaro reduced the scoreline to 3-2 in the 56th minute, but Oshimen restored Flying Eagles two goals lead for 4-2 in the 72nd minute with Abdullahi getting the third goal for his team.
The Nigeria U23 team had lost 2-1 to the same team in a friendly played in April.
The Dream Team Vi are expected to depart for Atlanta, USA to continue preparations for the men’s football tournament of this year’s Olympics on July 2, while the Flying Eagles step up preparations for their Afcon U20 qualifier against Sudan.
