 In 1974–75 Ethnikos made its best challenge for the league championship in the modern era.That season Ethnikos was winter champion, going undefeated through the first half of the season, but they could not keep up the pace and ultimately finished 4th (1 point behind PAOK for 3rd place and a UEFA Cup berth), while Olympiacos took the championship.Though never making another legitimate challenge for the league championship, Ethnikos remained consistently competitive during the 1970s, never finishing outside of the top 10.
