Morocco have become the first country to qualify for the semi-finals of a World Cup after they defeated Portugal 1-0 on Saturday.
The former European champions almost took the lead, but Yassine Bounou made a fine save to deny Joao Felix.
The Atlas Lions then took the lead through Youssef En-Nesyri.
The Sevilla striker rose highest to head past a stranded Diogo Costa.
It proved to be the only game of the encounter, as the North Africans repelled the Portuguese onslaught to create history.
Morocco will now play either France or England for a place in the final.
