Referee Maguette Ndiaye goes to have a look at a pitchside monitor. What a start this could be for Morocco.

A bright start for Morocco. Ayman Ashraf may well have conceded a very, very early penalty, sliding in on Achraf Hakimi.

It looks rash.

Here we go. Morocco get us started.

Who is going to make themselves a hero today? It's Egypt in the red, Morocco in their change colours of white.

The way the draw has panned out it could lead to Liverpool team-mates - Egypt's Mohamed Salah and Senegal's Sadio Mane - meeting on opposing sides in the final.

As you can see in our clips below, both men played key roles in their respective last-16 victories.

The Soufiane Boufal we are seeing at this Africa Cup of Nations is very different from the one we watched during his time at Southampton, where we only saw glimpses of his talent.

Here in Cameroon he has been a lot more consistent and a lot more influential for Morocco as well as scoring twice.

Morocco coach Vahid Halilhodzic says he has simply helped Boufal, who now plays in France's Ligue 1 for Angers, 'become more efficient.

Both men said the outcome of this quarter-final against Egypt will depend on 'small details'.

The stadium is less than a third full - but there are noisy pockets of both Morocco and Egypt fans with their flags.

Seems though that the ranks of the Egypt fans are about to be boosted - a colleague outside the ground says another five bus loads have arrived and are on their way in.

This is how the stadium looked a couple of hours ago...
