Holders Al Ahly and ASEC Abidjan booked their semi-final places in the CAF Champions League, but there was a marked contrast in the style of their respective performances on the penultimate weekend of the league phase.
The two other berths will be decided this coming weekend in direct head-to-head clashes that promise a dramatic twist to a continuously unfolding drama.
ASEC were rampant at home again, where they had two won their previous two Group B games by three-goal margins. On Sunday they went even one better, hammering Orlando Pirates of South Africa 4-0 to ensure they finish top of the standings.
This confirms not only a place in the last four but also home advantage in the second leg against the runner-up from Group A. Yet ASEC toiled for 43 minutes before finally breaking down the Pirates' defence, taking advantage of a corner kick when Foneye Die, making the most of a rare appearance in the starting line-up, got up above the South Africans' defence to direct the ball firmly into the net.
Eight minutes after half-time, Die provided an almost exact replica with another wonderful header, again from a corner, connecting even more fiercely with the ball as Pirates' Congo-born goalkeeper Francis Chansa was left stranded for a second time.
From then on, it became a spectacle of pure entertainment for the ASEC fans in a match which had been billed as a 'revenge' encounter as a result of a famous Pirates victory in Abidjan in 1995, when they wrestled the old African Champions Cup away from ASEC.
Defender Dacosta Goore scored the third goal with an easy tap-in, reacting first when the ball came back off the crossbar, and the fourth and final nail in the South Africans' coffin was hammered in by substitute Koffi Konan in stoppage time.
With ASEC now safely through, the runner-up berth in Group B will be decided this coming Saturday.
Tributes to Abdelwahab
Pirates must now win to stand a chance, while Enyimba need only a draw after the Nigerians scored with literally the last kick of the game - a fierce thunderbolt from Louis Otanwa - to clinch a home win over Hearts of Oak on Sunday.
It was a major relief after a frustrating afternoon for the Nigerians, who had drawn their previous two matches in Aba. The win puts them into second place in the group, two points above Pirates in the standing.
Elsewhere, emotions ran high as Al Ahly beat CS Sfaxien of Tunisia 2-1 in their top-of-the-table clash in Group A. It was the first outing for the Egyptian club since defender Mohamed Abdelwahab tragically collapsed and died during training and, in tribute, the home players wore black armbands, carried large posters of the late star and chanted his name after each goal.
Mohamed Aboutrika kissed his armband after scoring the opening goal in the 29th minute and then burst into tears. A second goal came 10 minutes later from Ahly's Angolan FIFA World Cup™ star Flavio but it was not plain sailing for the hosts, who weathered a late storm after Sfaxien scored in the 85th minute through Tarak Ziad.
Before the start of the game in Cairo, Sfaxien had needed just one point to go thorough to the semi-final and still look well placed to advance as they await a home game against Asante Kotoko on Sunday.
Kotoko's hopes were kept alive as they came from a goal down after just four minutes in Obuasi to win 2-1 against JS Kabylie, who were eliminated as a result.
Hamza Yacef put the Algerians into a surprise lead with his sixth strike of the campaign but two marvelously-taken goals by Nana Arhin Duah ensured home success for the Ghanaian hopefuls.
