The record seven-time winners bounced back from their 1-0 defeat to Nigeria in their tournament opener by beating Guinea-Bissau 1-0 courtesy of a volley by talisman Mohamed Salah in the 69th minute from a chipped cross from Amr El Soleya.

However, controversy surrounded the decision to rule out Mama Baldé's supposed-equaliser eight minutes from time.

The winger had regained the ball while trying to get past Egyptian defender Omar Kamal in a scrappy challenge, before playing the ball on the outside of his foot and striking with a curling effort past the goalkeeper.

Egypt's players protested the goal, with VAR controversially deeming the coming-together between Baldé and Kamal as a foul by the Guinea-Bissau player.

A victory over Sudan will seal Egypt's spot in the last 16.

Nigeria eased into the last 16 with a straightforward 3-1 victory over Sudan.

After three minutes Samuel Chukwueze got the Super Eagles off to a perfect start, controlling a Moses Simon pull-back to slot home from within the 18-yard box.

They doubled their lead when Taiwo Awoniyi unknowingly headed the ball into the net after a pinball of headers ended with Nigeria's second goal, right before half-time.

Simon then made it three almost straight from the restart of the second half, putting any doubt aside, despite Sudan's Khedr Safour Daiyeen scoring a 70th-minute penalty following a challenge from Ola Aina.

It puts Nigeria top of Group D with a maximum six points so far.
