The 14-year-old Daispangos was "enchanted" from the technical football AEK were playing at the time and set a goal to one day wear the yellow-black jersey and become a teammate with the players that looked like heroes, in his childish eyes.

On 8 November 1931, AEK won their first ever trophy, defeating Aris with 5–3 at Leoforos Alexandras Stadium in the Greek cup final, with Daispangos being one of the protagonists of the game alongside Giamalis, Negrepontis and Baltas, who scored a brace.

In 1948, when Jack Beby arrived to coach AEK, he received a young team from Daispangos, such as Emmanouilidis, Parayios, Oikonomou, Sevastiadis, Darakis, Papatheodorou and Poulis, with some of players being already international.

On his side throughout his career were the then curator, Nikos Goumas and the vice-president of AEK, Konstantinos Skouras, father-in-law of Sokratis Kokkalis, the later President of Olympiacos.

Daispangos came back to AEK on the condition that he would work alongside Tzanetis asking Goumas to take over again the academies, as he considered that they were the weakness of the club.

In his third and final term, he brought out footballers, such as Karafeskos, Stathopoulos, Simigdalas, Sevastopoulos, Pomonis, Kagianas, Andrikoulas, Kritikos, Lavaridis, Maniateas, Karapoulitidis, Sarris, Kyrmizas, Karakidis, Stefanou, Thivaios, Triantafyllou, Liakouris, Istorios, Psychogyios, Theodoridis, Moschakis, Papaioannou, Giannopoulos, Karoulias, the Karypidis brothers, Papagiannis and Kontopoulos.

In his 19-year presence on its infrastructure departments, AEK wοn 18 titles in total:[9] Daispangos was one of the founding members of the Hellenic Coaches Association, which served for more than a decade as its General Secretary.

Moreover in 1967, he sat on the bench of the team in the away games of the Balkans Cup against Vardar, Farul Constanța and Olimpija, since the then coach, Jenő Csaknády could not enter the Eastern states.
