Former Nigerian manager, Adegboye Onigbinde has charged Super Eagles to maintain 100% concentration against the Harambee Stars of Kenya.
.
The reigning African champions are pitched against the East African side in a 2014 Fifa World Cup qualifier at the UJ Esuene Stadium, Calabar on Saturday.
.
Onigbinde said the Kenyans are a tough-skinned side, warning the Eagles to keep close watch at them till the game is blown off.
.
"The East Africans have stamina, so even if we're leading them with a wide goal margin we must not lower the throttle or relax till the end of the match.
.
We must maintain 100% concentration, no form of complacency throughout the duration of the game.
.
"I'm optimistic of victory for the Super Eagles but we must work hard for it. It won't come on a platter of gold.
.
"I don't think there are many do's and dont's against the Kenyans, we must face them squarely as a fresh side and not what they were in time past.
.
"Kenya of yesterday is history same as Nigeria at 2013 Africa Cup of Nations in South Africa, those factors may not be relevant when both sides hit the pitch to jostle for the World Cup ticket.
.
"So we must tackle them with every amount of seriousness, we must not for any reason underrate them. They're not in Nigeria for sight-seeing but possibly beat Nigeria and chance qualifying for the World Cup.
.
"If we're alert, get our acts right, we'll grab the maximum points," he said to supersport.com. Nigeria lead their World Cup group on four points while their opponents, Kenya are at the rear on one point from two matches.
