Zanaco beat Cotonsport 1-0 to become the first Zambian club to win a continental fixture away in Cameroon.
Furthermore, the victory saw unbeaten Zanaco take full command of Group D on 10 out of a possible 12 points with two matches left.
A second half stoppage time goal from midfielder Saith Sakala handed Zanaco the triumph against the 2008 CAF champions League runners-up and in the process eliminate their winless hosts from the quarterfinal race in Group D.
“This win is a motivation for us to even push more in the remaining two games. It has put us in a good position to qualify to the quarterfinals,” said Numba.
A draw on July 1 at home against the record 8-time African champions Al Ahly of Egypt will suffice to confirm Zanaco’s debut qualification into the final knockout round of the CAF Champions League.
Al Ahly are 2nd on 7 points, one point more than 1992 winners Wydad Casablanca of Morocco who beat them 2-1 in Casablanca on Tuesday.
Zanaco will travel to Wydad on July 9 for their final Group D match.
Numba’s side began their Group D campaign with a 0-0 away draw against Al Ahly on May 12 in Alexandria.
Zanaco then stunned Wydad 1-0 in Lusaka on May 24 to collect their first Group D victory.
