The Eagles made four changes in their starting eleven with Ahmed Musa, Kevin Akpoguma, Moses Simon, and Kenneth Omeruo coming on.
Also, Genk striker Cyriel Dessers and CSKA Moscow winger Chidera Ejuke made their debuts for the Super Eagles coming on in the second half.

In the 44th minute, Mohamed Drajer equalized for Tunisia as he slammed the ball into the roof of the net off a cross from the left.
Akpoguma almost equalise for the Super Eagles in one minute of first-half added time, but his goal-bound header from a corner was cleared off the line.
The Eagles had a positive start three minutes into the second half but Iheanacho’s header from a corner went just over the bar.
In the 57th minute, the Eagles made their first change with Chidozie Awaziem coming on for Balogun.
They made another change on 66 minutes as Sanusi went off with a suspected groin injury for Jamilu Collins.
With 20 minutes left Dessers replaced Musa for his debut in the Eagles colours.
