Russian Federation are the hosts for World Cup 2018, which kicks off in just six days time - but they are also the lowest ranked team in the competition. Egypt's hopes largely rely on one superstar, Mohamed Salah, but he is out for this match with an injured shoulder.
Martinez made a host of changes at the break and it impacted Belgium's fluency, though substitute Fellaini added a third in the 92nd minute. However embattled coach Roberto Martinez has yet to win over fans, and is sweating over the fitness of key defenders Thomas Vermaelen (thigh) and Vincent Kompany (groin), both injured.
Eden Hazard has his own World Cup campaign with Belgium to focus on but he's still finding time to support another nation in a different group, it seems. "There are many aspects that we need to improve".
"Mo Salah is not just a good player, he's an outstanding footballer, he's a world class footballer after what he's done this season", Martinez said. "But what I like is that when we make mistakes we've got the togetherness to try to overcome them and I don't think we had that before and that's very pleasing". Coach Roberto Martinez named Los Angeles FC defender Laurent Ciman as a replacement if Kompany is not fit to play in Russian Federation.
The Chelsea forward, 27, turned from provider to finisher as he side-footed Yannick Carrasco's cross past the sprawling El-Hadary from close range.
Belgium eased past Egypt 3-0 in Brussels to extend the north African side's winless streak since qualifying for the tournament in Russian Federation starting next week.
Belgium will complete their warm-up fixtures with another home tie, against Costa Rica, next Monday after which Martinez must decide on his final 23-man squad for Russian Federation.
Now rehabbing his shoulder, the 44-goal hero has been included in Egypt's squad for the World Cup - which gets underway against Uruguay in the second game in Group A on 15 June.
"I don't think we are physically, tactically and mentally ready. and that's why the Costa Rica game will be important", he said.
