Mosaad Nour, is one of the most skilled Egyptian football players and of course the most famous and popular player for Al-Masry throughout its long history.
"Kastan" moved to Al-Masry in 1972 and spent 13 years with The Club before he retired in October 1985.
Unfortunately Mosaad Nour could not win any titles with his beloved team Al-Masry although he was so near from capturing the Egypt Cup for two consecutive years in seasons 1982/83 and 1983/84. Meanwhile "Kastan" was so near from winning the Egyptian League in season 1983/84 but he missed the chance.
Mosaad Nour refused all the offers to leave his team, although he had many offers to move to either Al-Ahly or Zamalek SC, and such manner was sufficient to make him the beloved star for Al-Masry's fans throughout the years.
