He was then transferred to the team of the neighboring village of Agios Dimitrios, with which he was crowned champion of the local second division.
A remarkable performance of Atmatsidis was when he made a double save on a penalty by Anastasiou and then on a shot by Tsiantakis in a championship match with OFI.
In January 2003 the Atmatsidis asked to be released to get more playing time and his contract was terminated by mutual consent.
In January 2014 he came out of retirement to play for local Herakleion based club Omonia NOVA Apolimantiki.
At November 1999, he decided to retire from the national team, as a sign of protest against refereeing in Greek football.
