[1] He then moved to the region's most prestigious club Levadiakos, making his debut in the Greek Alpha Ethnki, the top-level football league in Greece.
After his retirement, Gonias worked as a football commentator for Greek television, while also professionally taking up Golf in Glyfada, Athens.
After an unrealized deal with Gamma Ethniki side Volos NFC,[5] Gonias was appointed manager of newly promoted Football League club Ergotelis in August 2017.
[6] Gonias' unique approach to the game was met with suspicion from Greek media at first, even more so as the Cretans struggled to earn points on the Table and became relegation contenders at an early stage during the tournament.
Despite criticism from local media, as well as a portion of the club's fans, who often demanded Gonias be sacked from his post,[7] Ergotelis' board placed their full trust in their head coach' work.
His unwavering approach to the game regardless of the opponent and match progression, has often been openly questioned by the press and fans as inappropriate for the realities of the second tier of the Greek football league system.
[15] Gonias has therefore built a reputation in Greece for his post-match analysis during statements to the press, and his tendency to get overly defensive when questioned about his tactics.
