Gernot Rohr’s men cruised to a commanding 4-0 victory in the first leg at Godswill Akpabio International Stadium on Saturday.
The win saw them climb to the second spot in the group standings with six points from three games, one point adrift of South Africa.
A back-to-back victory over the Mediterranean Knights will brighten the Super Eagles’ chances of securing a place in Cameroon next year after missing out on the last two editions of the tournament.
And the former winger, delighted with the showing in Uyo, has highlighted areas the three-time African champions must work on.
“We won the game fantastic. They did not expect we are going to score four goals against them which is massive,” Lawal told Goal.
“We did not allow them to play their game. The Group is very tight and we have to think of the next game. We have to approach the game with caution because you can see Libya were very smart yesterday.
“We must play as a team. When we have the ball we must try to keep it. In football now you can never tell, every team wants to win, it does not matter whether you are playing home or away.
“We don’t know what is going to happen on Tuesday but I hope we win once again.”
