On 20 December 2016, Chatziisaias returned to the first team of PAOK immediately, in order to replace experienced international Georgios Tzavellas.
Then, there were only stoppers Stelios Malezas, José Ángel Crespo and Fernando Varela in the current squad of the club, so his return was necessary ahead of the upcoming difficult matches in January.
[6] On 30 June 2018, Greek central defender Chatziisaias will finally still be a member of ambitious Atromitos, on loan from PAOK until the end of 2018–19 season.
The 26-year-old scored one goal (at 1–0 away victory over Asteras Tripolis in February) at 32 performances in the domestic competitions with the shirt of Austrian manager Damir Canadi's team during 2017–18 season.
[7] On 23 July 2019, Çaykur Rizespor announced the signing of Chatziisaias with a transfer fee in the region of €500,000, after the acquisition of Enea Mihaj from Panetolikos.
