That gave the DR Congo side the win, despite being hampered by the absence of two key players - top scorer and captain TresorMputuMabi and midfielder Guy Lusadisu.
The closest the hosts came to breaking the deadlock came at the end of the first leg as TresorMputuMabi, who scored the crucial away goal for Mazembe in Nigeria last weekend, found Kalauyituka Dioko, but his header was saved by Augustine Brown.
