Zambia is drawn in Group B along with Cape Verde, Democratic Republic of Congo and Tunisia and has set up a training camp in South Africa.
Janza told fazfootball.com when announcing the squad in Johannesburg that his selection was based on how each player performed in training.
“It has been a very competitive training camp where every player was trying hard to make the grade but unfortunately we only have 23 places available and as such we had to part company with the four. This selection is based purely on current performance for each player,” Janza said.
The four players who were left out are striker James Chamanga, goalkeeper Toaster Nsabata, defenders Aaron Katebe and Bronson Chama
