Tunisian side, Etoile du Sahel thrice came from behind to beat Nkana of Zambia 4-3 in their Group B thrilling encounter on Saturday in Sousse.
The 2006 CAF Champions League winners kept intact their unbeaten run at the group stage of the second-tier continental club championship, and move top on five points, one point richer that Egyptian giants Al-Ahly who play as guests of Ivorian side, Sewe Sport on Sunday in Abidjan.
After just seven minutes, the Zambians went up thanks to an own-goal after hard-pressed Etoile du Sahel defender Ghazi Abderrazak inadvertently shot into his own net in an attempt to clear the ball.
The hosts never looked back despite a goal down, making several raids into the half of the visitors in their quest to break even. The moment did arrive on 20 minutes when Youssef Mouihbi was fouled by Nkana defender Joseph Lungu in the vital area for a penalty which was converted by Algerian recruit Baghdad Boundjah to draw even.
The Nkana attack led by Evans Kangwa and supported by Ronald Kampamba gave the host's defence sleepless night and anytime they moved upfront got them wanting.
On the half-hour mark, Kangwa profited from a poor clearance from captain Seif Ghezal to give the Zambians a 2-1 lead at half time.
The introduction of Alkhaly Bangoura for Ghezal by Etoile du Sahel coach Roger Lemerre at the start of the second half changed the face of the game for his side
Eight minutes after the break, Guinean-import Bangoura restored parity with a tap in after Abderazzak's goal-bound shot bounced off the upright.
Nkana were undaunted and went up for the third time on 79 minutes through Derrick Mwanza from the spot.
The lead lasted for only 60 seconds, only for substitute Lassad Jaziri to score to make it three-all before Bangoura connected home from a rebound after Jaziri's free-kick kissed the upright to ensure a dramatic victory for the 'Diables Rouges'.
