El Hadary was 45 years and 161 days old when he took to the field as the two already-eliminated teams in Group A played only for pride.
Egypt gave us one of those moments by starting 45-year-old goalkeeper Essam El-Hadary in between the pipes against Saudi Arabia.
The Green Falcons were, however, awarded another spot-kick in first-half injury-time when Al-Muwallad was adjudged to have been dragged down inside the area by Ali Gabr and, upon consultation with the Video Assistant Referee, the award stood.
Egypt finished bottom of Group A and failed to pick up a point, losing against Uruguay, Russia and Saudi Arabia.

Salah doing what he does best... scoring lovely goals.
He soon underlined his importance on the pitch though, calmly lifting the ball over advancing goalkeeper Yasser Al Mosailem in the 22nd minute after latching on to a raking pass forward.

El-Hadary has been a member of Egypt's national team since 1996 and has made over 150 appearances for the team.
"There is not much between our three goalkeepers but he was the right person to play today", said Cuper.
And there was to be last-gasp heartbreak for Egypt as Salem Al-Dawsari swept in a 94 minute victor for their opponents.
Saudi Arabia tried to test Al Hadary early, with Hussain Al Mogahwi attempting a speculative chance from distance in the third minute, but it hooked well wide of the goal.
Cavani sealed the win with a tap in from close range for his first World Cup goal.
