Angola have won three of their four games in the competition.
Lookman reckoned Pedro Goncalves’ side will be a tough nut to crack for the Super Eagles.
“Angola are a good team. We’ll analyze them and prepare. The further you go, the tougher it gets so we’ll take it game by game,” Lookman told reporters.
The Atalanta winger, who is playing in his first major tournament with Nigeria said he is enjoying every bit of his time in Cote d’Ivoire.
“I love this atmosphere, it’s incredible. Our fans pushed us to the end because this was Cameroon, and when you wear the Super Eagles shirt, some games resonate more than others.”
