Mokwana has been doing great for Esperance since he joined the team in August last year after his potential move to Kaizer Chiefs failed to materialise.
The victory against Tunisien meant that Esperance, who are the most decorated club in Tunisia, have now won the Tunisian Super Cup seven times.
The 25-year-old speedy attacker has so far managed to score six goals across all competitions for the four-time Caf Champions League winners.
