The Red Devils also won the 2019/2020 Egyptian Premier League and the 2019-20 Total CAF Champions League titles before.
Al Ahly defeated Talaea El Geish 3-2 on penalties after a one-all stalemate in extra time at the Alexandria based Borg El Arab Stadium.
Their victory means that they extended their record winning to 37 Egypt Cup titles, ten more than arch-rivals Zamalek.
Mahmoud Abdel Moneam “Kahraba” came from the bench to give Al Ahly the lead after 65 minutes.
However, Nasser Mansy equalized for the army side El Geish two minutes into injury time.
There were no more goals in the extra time, as the game headed to penalties which smiled to Pitso Mosimane’s men.
As he did many times this season, Al Ahly skipper and goalkeeper Mohamed Elshennawy was his side’s hero saving Mansy’s kick from the spot.
Meanwhile Khaled Setouhy and Hussein Elsayed efforts rebounded from the woodwork, while Islam Mohareb and Mostafa Gamal scored for the army club that was playing their first ever Egypt Cup final.
Ayman Ashraf and Mohamed Magdy “Afsha” whose 86th minute goal handed Al Ahly win over Zamalek in the CAF Champions League final last weekend) missed for Al Ahly.
Meanwhile, Ali Maaloul, Amr El Soleya and new recruit Badr Benoun scored for the Red Devils.
It was Al Ahly’s first Cup glory since 2017, while completing their 15th domestic League and Cup double.
It’s also the club’s second League, Cup and CAF Champions League treble after 2005/2006 season.
The Red Devils now shift their attention to the new 2020/2021 Egyptian Premier League season, set to kick off next weekend.
