Born in Lebanon, Saad's family moved to Australia when he was a child. An attacking midfielder with a good eye for goal, he represented the Australian national team in a match against Russian club Torpedo Moscow and earned his first full cap against Malaysia two years later. After a six-year gap, he was recalled by then Socceroos coach Terry Venables for three games in 1998. In all, he played six times for his country, earning four full caps.
Shortly after the 1994 triumph, Saad was charged with match-fixing in Singapore. He has always maintained he was innocent of this charge. During his trial, he admitted that he had been approached by his teammate Michal Váňa, who asked Saad to help him win certain matches by large margins during the 1994 season as Váňa was betting on the outcome of the games. However Saad stated that he had refused to help Váňa try to fix the scores of any games, and had merely told Váňa that he would try to help the Singapore team win the games by as many goals as possible as this was his job. Saad had not reported Váňa's requests or his knowledge that Váňa was betting on games to team officials or the authorities, but stated during his trial that he had told Váňa that he should stop betting on matches. In June 1995, the Singapore courts convicted Saad of match-fixing and fined him S$50,000. He then received a global playing ban from FIFA. Saad continues to maintain that he was innocent of match-fixing, and that he merely knew that Váňa was betting on the outcomes of matches but was not involved himself. Speaking about the verdict in an interview in 2009, Saad said: " approached me once and said 'you score goals?' and I said 'of course I score goals, I'm a striker'. And so that conversation was taken out of context. There was no money received or nothing like that. I don't know how they built a case, I think it was a technical thing. I'm not a lawyer."
Saad was coach at New South Wales Premier League side Penrith Nepean United, and in 2009 was named as Technical Youth Director by Sydney Olympic FC. He has also been the head coach for the Australian Deaf Football team. Saad has also served as the head coach of the GIS Academy at the Garden International School in Kuala Lumpur, Malaysia who unfortunately lost in the ISAC division 2 finals against fierce rivals KLASS. With Goals from Eamon and Connor as well as saves from Alex proving to be the decisive factors. Following his conviction for match-fixing in Singapore, he received a lifetime ban from the Football Association of Singapore, but this was lifted in 2009 and he is now able to be involved in footballing activities in Singapore again.
