Favour Daniel scored the only goal on Sunday as Nigeria's Golden Eaglets got off to a winning start over Zambia in their first game at the Africa U17 Cup of Nations taking place in Algeria.

His solitary strike gave Nigeria all three points in a largely average encounter that opened the campaign in Group B.

Both teams hit the woodwork in the first period and Abubakar Abdullahi saw his efforts saved twice as Nigeria piled on the pressure.
