Match preview
Zambia showed great mettle to emerge triumphant from a thrilling five-goal contest against Sierra Leone when the teams locked horns on September 10.
Having thrown away 1-0 and 2-1 leads, Avram Grant's men were set for a share of the spoils on home turf, only for Kings Kangwa to grab the winning goal five minutes from the end of normal time.
That ended a dismal run of nine competitive outings without a victory for the Chipolopolo, who had also come away empty-handed from six consecutive matches prior.
While Grant saw his side fail to keep a clean sheet for the 15th straight game, he would have been pleased by their attacking output after five straight games without a goal.
Currently second in Group G of the AFCON qualifiers, Zambia could potentially pull five points clear of the chasing pack before next week's trip to Yaounde for the second leg of their double-header against Chad.
Chad's downward spiral continued in last month's encounter against the Elephants of Ivory Coast, which ended in a 2-0 defeat at Stade Ahmadou Ahidjo.
After setting up Jean-Philippe Krasso's opener on the stroke of half time, Oumar Diakite grabbed a second-half clincher in the 55th minute to leave Kevin Nicaise's men with what proved to be an insurmountable task.
It is now three defeats and a stalemate from the last four matches for Les Sao, who have exhibited glaring deficiencies at both ends of the pitch in that time, with five goals conceded and none scored.
Still yet to feature at an AFCON tournament proper, Chad, who sit bottom of their qualifying group, are running out of time to save their continental dreams ahead of Friday's clash in Ndola, where they will be aiming to pick up only a second away triumph since 2015.
