The 1928–29 Panhellenic Championship was not held due to serious financial problems, as the organization of friendly matches between the POK members had led the HFF to economic and competitive decline. The return of the members of POK to the HFF in July 1928 and the desire of both sides to hold the championship did not succeed, as the championships of Athens, Piraeus and Macedonia were held, in which Panathinaikos and Olympiacos alongside Ethnikos Piraeus and Aris finished first respectively, but there was a significant delay in their completion, as a result of which the Panhellenic championship was not held, since the summer had already arrived and there was a strong fear of another financial failure.[1][2]

^ abIn the ranking matches, both of them achieved a victory and as stipulated by the HFF legislation, 2 ranking matches were re-defined. The 3rd match ended a draw and a 4th match was held in the summer on July 14, 1929 and if it ended in a draw it would be led to extra time.[3][4] The game was suspended at the 87th minute because of fan invasion, while the score was 1–1. In the end, the Piraeus' Association declared both clubs co-champions[5][6] in order not to repeat the incidents of the previous periods, with the departures of any of them.
*The 1st half ends with 1–0 in favor of Olympiacos and in the 2nd half Ethnikos manages to equalize. Ethnikos also scored a second goal after a clash between the goalkeeper of Olympiacos and 3 players of Ethnikos, after he had previously blocked the ball and thus was considered a foul. The game continues until a fan invades the field and attacks an Olympiacos' player and then a general conflict ensues as other fans invade. In the end, the game never continued and did not go to extra time and it was stopped permanently,[7]
