Sfaxien lifted the cup in 2007, a feat they are attempting repeat
Tunisia's Club Africain overtook local rivals CS Sfaxien as leaders of Group A of the Confederation Cup after a 2-1 win away to Angola's InterClube.
The win in Luanda put Club Africain top on goal difference with two group games to go.
Sfaxien and Club Africain face each other in the last round of matches, in what is shaping up to be the crunch decider of the group.
Sfaxien are aiming become the first club to successfully defend the title, after beating Egypt's Harras El Hadood 1-0 on Friday, courtesy of a fortuitous long range winner from defender Issam Merdassiof.
Hadood goalkeeper Mathurin Kameni allowed Merdassiof's free kick to slip under his body and into the net at the 20,000-seat Taieb Mhiri Stadium in the Mediterranean town of Sfax.
Kameni later capped a miserable outing when he was sent off a minute from time for fouling Ghanaian Agyemang Opoku on the edge of the penalty area.
Sfaxien's win on Friday gave them swift revenge, after crashing 3-1 at African debutants Harras last weekend.
Club Africain and Sfaxien are now both on seven points and Harras on six, after four matches, with InterClube on three.
In Group B, Etoile du Sahel of Tunisia lost 2-0 to third-placed Al Merreikh of Sudan.
Endurance Idaho scored twice either side of half-time to avenge last weekend's 2-1 defeat to the same opponents.
Algerians JS Kabylie took their own revenge on Ghana's Asante Kotoko beating them 2-0 on an artificial pitch in Tizi Ouzou.
The win reversed last week's 3-1 defeat by the Ghanaian side, and puts all four teams in Group B level on six points.
The winners of the two groups meet each other in a two-leg final.
