Morocco became the first African nation to reach a World Cup semi-final and ended the hopes of Cristiano Ronaldo’s Portugal.
Striker Youssef En-Nesyri scored the winning goal in the first half, leaping highest to beat goalkeeper Diogo Costa to the ball and heading in to spark pandemonium at Al Thumama Stadium.
The north African side’s supporters populated most of the venue and joyously celebrated their breakthrough moment on the global stage.
Ronaldo came off the bench in the 50th minute to equal the men’s all-time appearance record of 196 in international matches, but he could not drag his side back into the contest.
Morocco, who will face England or France in the last four, were happy to play on the counter and grabbed the opener just before the break when En-Nesyri headed in from Yahya Attiyat-Allah’s cross.
Portugal skipper Bruno Fernandes came agonisingly close to levelling just minutes later but a brilliant individual effort struck the crossbar.
Decimated by injuries, Morocco sat back for the majority of the second half and Yassine Bounou brilliantly tipped over Joao Felix’s drive – the closest they came to an equaliser.
Morocco striker Walid Cheddira was sent off for a second yellow card in eight minutes of additional time but Portugal could not find the equaliser as their last-four hopes were dashed.
Three African sides had previously reached this stage of the World Cup but none had progressed any further. Until now.
The marvellous Moroccan players and fans rejoiced as En-Nesyri’s header on 42 minutes proved to be the pivotal moment.
Fans whistled and jeered every pass the Portuguese players made and then the rowdiest section behind the goal seemed to suck the ball into the net.
Walid Regragui’s side were missing West Ham’s Nayef Aguerd, Bayern Munich’s Noussair Mazraoui and lost captain Romain Saiss to injury early in the second period.
