Milan in the Intercontinental Cup. On 23 June 1973, AEL wins Kallithea 3–0 and seal typically the promotion in the First National, finishing first with 98 points, ahead of the second renaissance Karditsa who finished with 89 points. The goals for AEL succeed by Pagkarliotas at 16', D. Seitaridis at 38' and Charitidis at 80'. AEL lined up on the field with the following players: Siavalas, Simantiris, Seitaridis M., Hill, Kyziroglou, Boutos, Charitidis, Cavoli, Rakintzoglou, Seitaridis and Pagkarliotas.. The team started the season 1973–74 at the First National, with the enthusiasm of a rookie, but clearly capable of material, grafted by the talent and quality players like Kyriakidis, Matzourakis and Dramalis in order to stay in the category. The course was based on the overall strength of the home ground and the final 9th position was considered highly successful. Karamfilovic was replaced (due to expired residence to the country that was not renewed for political reasons), by the Bulgarian coach Ivan Kochev. However, a team built on legionnaires without first having obtained the financial strength and solid basis, couldn't have long term evolution. So, the very next year problems started, which led to hasty choices, judgments and frequent upheavals in all levels.

More experienced Siavalas, Boutos, Lellis, Stergiadis, and Argiroulis formed the backbone on which, as time went on, had positive impact for the team. Of course, the great breakthrough was made a year later by President Elias Kelesidis and his colleagues in the administration, when they decided to promote to the first team all of the youth squad of AEL, and collect all the talents that admittedly stood well in the Thessalian prefecture. Thus, on 26 May 1977, in a friendly match against AEK (the first under spotlights in Alcazar stadium), AEL lined up with Anagnostou, Giannis Mousouris and nine native players from Larissa's region. Among them, unknown then, Takis Parafestas, Giannis Valaoras, Dimitris Koukoulitsios and Christos Andreoudis. That summer of 77, rookies including Dimitris Mousiaris and Giannis Valaoras signed a professional contract. These two, along with Koukoulitsios and Ilias Selionis, became members of the youth National teams. On 18 June 1978 AEL traveled in Thessaloniki, and celebrated on the
