TP Mazembe from the Democratic Republic of Congo and Club Africain of Tunisia drew 1-1 on Saturday in a CAF Champions League qualifier between former title-holders.
Kazema Baso put hosts Mazembe ahead after 38 minutes in the southern city of Lubumbashi, only for the visitors to equalise one minute later through Burkina Faso international Alain Kante.
Drawing in central Africa established the Tunis club as slight favourites to win the return match on 25 October and qualify for the group phase.
Club Africain hammered Uganda opponents SC Villa 7-3 on aggregate in 1991 to become the first African champions from Tunisia.
But they have consistently disappointed in African campaigns since, apart from 2011 when finishing CAF Confederation Cup runners-up.
Mazembe have twice achieved back-to-back titles in the premier African club competition. The most recent of five Champions League triumphs came 11 years ago.
