In January 2015, Pantelis Hatzidiakos, who moved from Panathinaikos to AZ as a youth in 2011, signed a three-year professional contract with the Dutch team. Hatzidiakos made his debuts with the club in both the Champions League and the Europa League matches. In the past, he was crowned Dutch champion with the AZ U16. In 2017 he helped Jong AZ win the title in Tweede Divisie and achieve promotion to Eerste Divisie.
He made his debut in the club, along with his first appearance in Eredivisie in a 2–1 away loss against PEC Zwolle as a substitute in the second half. On 3 December 2017, the 20-year-old Greek international central defender, scored his first goal in the Eredivisie, in a 2-0 away win against VVV-Venlo. He sealed the win in the 84th minute "With an excellent shot at the height of the area, and this is not the first goal of his career, as he scored in the KNVB Cup against MVV Maastricht in September." With this victory, Alkmaar reached 6 consecutive wins in the League. He started the 2018–19 season as the undisputed leader of the AZ's defence.
As a result of his exceptional performances he was called in the Greece U-21 team from Antonis Nikopolidis for the 2019 UEFA European Under-21 Championship qualification match against San Marino and Czech Republic on 22 and 27 March 2018 respectively.
