Super Eagles wasted no time in taking the lead when Alex Iwobi smashed home a cross from Samuel Chukwueze less than two minutes into the game.
Victor Osimhen doubled the lead for Nigeria when he finished off a perfect cross from Zaidu Sanusi who made a strong run from deep.
With Sierra Leone still trying to match the pace of the Nigerians, Iwobi finished off a passing sequence with a curved effort which effectively put the game to bed for the Super Eagles.
That lead was quickly extended when Chukwueze raced on to a pass from Osimhen to finish with aplomb after taking out three Leone Stars defender.
With scores at 4-1 in favour of Nigeria, Chukwueze was robbed off the ball after a poorly hit pass from Musa and the Leone Stars took advantage of it to pull a goal back.
They made Nigeria to pay for another sloppy defensive display to pull another goal back with Semi Ajayi who replaced Leon Balogun guilty of ball watching.
Not long from the second goal and with the Nigerian defence all over the place, Sierra Leone pounce to score another before finally drawing level leaving the Eagles in disarray.
