Zambian coach Herve Renard said his side are determined to defend their title ahead of their opening African Cup of Nations match on Monday.
The Copper Bullets won the competition last year after beating Ivory Coast on penalties and are preparing to face Ethiopia in the first Group C game of the tournament.
While Renard is confident his side can repeat their heroics from last year he concedes they cannot afford to live in the past.
"We are here to defend our title. It's a big honour for us to have the title of African Cup of Nations champions in 2012," he said.
"We close 2012 and like I have said to the players, it's written on the board now, never live in the past always learn from it. The past is finished, now is the future and the future starts tomorrow."
Nigeria threaten to pose the biggest challenge for Zambia in their group and although Renard is wary of the Super Eagles, he insists he is only focused on their opening game against Ethiopia.
"We know Nigeria, we know their past, they are a very strong team who didn't lose in 2012, we saw their friendly game but at the moment our focus in on Ethiopia tomorrow," he said.
