Mazembe beat USM Algiers of Algeria 2-1 away in a first leg, final match.
Kalaba scored the first goal in the 27th minute against 10-man USM in Algiers before Tanzanian striker Mbwana Samatta added the winner from the penalty spot in the 79th minute.
Kalaba was the only Zambian player in Mazembe’s final 18 for the match.
