Former Nigeria international, Garba Lawal, has said the 2018 World Cup qualifying games between the Super Eagles and African champions Cameroon, will be difficult.
The Eagles will take on the Indomitable Lions in a double-header on August 28 and September 2 this year.
Nigeria needs at least four points out of six to confirm their play at the World Cup in Russia.
“I’m happy for Cameroon emerging as African champions. Nobody gave them a chance, but that’s football for you,” Lawal told Goal.
“Now we are playing Cameroon in a double header [qualifier]. We’ve played two games and got six points from them.
“I must say the coaches and players have done a fantastic job so far. But they need to remain focused and not relent.
“They need to concentrate and maintain what they’ve started in the best possible way against them because one game can change everything.”
“Cameroon are a physical side and rely solely on their physical strength. But we [Nigeria] believe in skill, mental and as well as physical aspects of the game,” he continued.
“Whenever they want to play Nigeria, they know they can’t match us, so they will do everything to kick and physically attack us in order to frustrate.
“Our players need to be ready for that because I believe the match will be very difficult, strong and competitive.
“They know it will be difficult to match us. At this point, we have no pressure and we can’t afford to get distracted except we want to throw those points away.
“He [Rohr] is a manager and the coach, and he knows better. He should keep on watching and getting his team together. He should not get carried away”, he added.
