Ghana coach Kwesi Appiah is confident the Black Stars can end a 31-year wait for an African title but admits the problematic left back position remains his major headache.
The Ghanaians have always been tagged as one of the favourite to win the title but have in the process flatter to deceive for the past three decades.
The four-time African champions have experimented with players for the problematic left back position over the last six years without huge success.
The likes of Razak Nuhu, Daniel Opare, Samuel Inkoom, Lee Addy, Nana Kwesi Asare and Massawudu Alhassan have all had a crack at the position.
German-based Hans Adu-Sarpei enjoyed a relative success at the left back role until age caught up with him but Esperance defender Harrison Afful has come into the fray to bring some sort of stability at the back.
With 45 days left for the start of the tournament, the Ghana trainer is hopeful of making history but having sleepless night about the back.
"My major problem is the left side and I must admit that I do not feel safe when the right back position either, and that is why, incidentally, I'm looking for solutions,” Appiah said
"It will be difficult but hardly impossible, and when I read the determination on the faces of our players and I see what we're currently providing, I think we can end this drought.”
The Ghanaians are housed in group B where they will play DR Congo, Mali and less-fancied Niger in Port Elizabeth.
The Black Stars last won the Nations Cup in 1982.
