This follows their hard-fought 1-0 victory over South Africa last Friday, secured by a first-half penalty from Liverpool star Mohamed Salah.
The win ensures Egypt's progression to the round of 16, with the Pharaohs sitting atop Group B on six points after also defeating Zimbabwe 2-1 in the opening round.
"I will introduce new faces during the game against Angola as it comes just 48 hours after today's match," Hassan was quoted by Ahram Online.
"We will do our best to confirm our lead in the group and prepare for the upcoming rounds."
Egypt dominated the first half against South Africa but came under pressure in the second after Mohamed Hany was shown a red card before halftime.
Despite playing with a man down, the Pharaohs managed to hold on for the win, demonstrating tactical discipline and resilience.
Hassan praised his players' performances, highlighting their ability to adapt to different challenges.
"We played the game against Zimbabwe as a final, managing a comeback and a win. We played a full half with only ten players and still secured the victory," he said.
"I thank all the players for executing our tactics well and closing down South Africa's players effectively."
The coach also acknowledged the support of fans during the tournament.
"I thank the Moroccan fans for their encouragement during the game. Since the draw was held in Morocco, we knew the game against South Africa would be difficult, as they have many talented players," Hassan added.
Reflecting on Egypt's journey so far, Hassan emphasized the team's flexibility.
“I am happy that we don't rely on a static tactic; we adapt our approach for every game,” said the coach.
