Esperance staged a historic second leg performance to crash Al Ahly in the final of the 2018 CAF Champions League
Saad Bguir in his first start of the campaign because of Franck Kom's suspension played the game of his life by giving the hosts the opener on the stroke of half time and he doubled the lead in the 54th minute.
Anice Badri completed the walllop to give Esperance a 4-3 aggregate victory.
They had lost the first leg 3-1, with Ahly converting two controversial penalties.
A dominant performance by the 'Blood and Gold' at the Stade Olympique de Rades ended a 10-match winless run against Ahly in CAF competitions that stretched back to July 2011.
Al Ahly's first-leg victory included two penalties that were confirmed with the use of Video Assistant Referee technology.
The Esperance fans were not only angry at both penalties but also with Ahly's Moroccan striker Walid Azaro, who was caught ripping his own shirt by TV cameras.
That incident led to Azaro being banned for both the second leg in Tunis and a further continental match in the future.
Esperance, champions in 1994 and 2011, will now take part in December's Club World Cup in the United Arab Emirates.
