Super Eagles' manager, Stephen Keshi has said its rather his side's AFCON group foes that should worry their heads at the forthcoming football hostilities in South Africa.
Nigeria is in Group C alongside Cup holders, Zambia, Burkina Faso and Ethiopia.
Keshi whose home-based players kicked off the AFCON training on Monday at the practice pitch, Abuja National Stadium said his concern is to raise a strong side that will challenge for the title at South Africa 2013.
"I don't need to worry my head over Zambia, Burkina Faso or Ethiopia. They should rather worry themselves about us.
"My main worry is to prepare the team adequately and come up with a squad that will give Nigerians the third Africa title in South Africa.
"You don't waste huge time thinking for yourself as well as others. You allow others think for themselves while you use your valuable time to do positive work," said the former Nigerian defender.
Keshi expressed satisfaction with the forms of the domestic players at Monday's training session.
"Training is turning out well, I pray it continues to progress as clock ticks for the AFCON 2013.
"Players responses are fine, I think they're picking the right mentality, I'm excited at the progress made," he said.
However, it was gathered that players returning from prolonged injuries may not make the cut for the AFCON game.
This thinking might threaten the AFCON chance of the likes of Joel Obi, Onyekachi Apam, among others.
