Egyptian Premier League
Al-Ahly's opening game of the Egyptian Premier League 2009–10 was on August 6 against Ghazl El-Mehalla. Al-Ahly's coach Hossam El-Badry, who took over the club following the departure of Portuguese Manuel José at the end of the previous season, employed an unusual 4-4-2 formation. Despite the bad opening of the season in the super cup defeat against Haras El Hodood Al-Ahly beat Ghazl El-Mehalla 2–0. Ahmed Hassan made the opening score after 40 minutes and Francis Doe brought the score up to two 66 minutes into his Egyptian Premier League debut. The next game was a narrow 2–1 win over Ittihad El-Shorta in an unbroadcast game on 19 August. Former Ahly player Ahmed Galal scored the first goal of the game after 31 minutes, but 4 minutes later Ahly's player Ahmed Hassan scored equalizing the score. In the second-half substitute Hussein Yasser scored Al-Ahly's second goal in the 80th minute to secure Ahly's second win of the season.
On 23 August, Al-Ahly played their third match of the season against Haras El Hodood in a 1–1 draw, Haras El Hodood player Ahmed Salama scored the opener 69 minutes in and Ahmed Hassan scored the equalizer nine minutes later.
