While DeMbare were outplayed by a well schooled home side, the task was made more difficult with some questionable officiating by referee Keita Yakhouba from Guinea.
Timire Mamvura was dismissed for picking up two yellow cards with the second in the second half.
When Mamvura left the pitch DeMbare were trailing by three goals but the hosts added three more to leave the visitors in tatters.
There were no questions about the first two goals that were scored by Walid Ichri and Karim Aouadhi but Yousef Msekni’s 34th minute strike was controversial.
Only 10 minutes into the match, Afful Harrison won a free kick on the left which was swung in by captain Khalil Chamem to the benefit of defender Ichri who jumped above everyone to nod in the ball.
If Dynamos had planned to be cagey, they were soon forced to amend that as they started playing more positively with the match bursting into life.
Dynamos had been warned about Youssef Msekni and he showed why they call him Messi here when he beat several defenders before running along the penalty box line, in true Messi style, only for his shot to be blocked by Washington Arubi but into the path of Karim Aouadhi who had the simplest of tasks to roll it in four minutes after the opener.
With Dynamos seemingly settling and starting to look like they could get a goal, the referee torched controversy when he allowed play to continue after Ocean Mushure had been elbowed by Yannick Ndjeng whose pass found Msekni for the dribbling ace to fire home with 34 minutes on the clock.
Dynamos protested both to the referee and fourth official but to no avail and Esperance were on their way to a big win.
With frustration creeping in, Dynamos players began to commit more fouls.
There were more heated debates and mini conferences than free flowing football in the first period.
In the second half, Dynamos organised themselves better but they never posed a threat to the goalkeeper Moez Ben Chifinya
Tannick Ndjeng added comfort to his team’s lead at the end of an Afful Harrison cross from the right, six minutes before the end.
Youssef Msekni played a one-two with substitute Iheb Msekni to split the defence for the latter to make the scoreline more emphatic with four minutes left.
The last goal was headed in by substitute Idriss Mhirsi just beating the final whistle.
