Career
Machairas started his career at the youth team of Levadiakos and signed his first professional contract in June 2009. He was promoted to the first team on October of the same year and made his debut on 25 October during a victorious home game against Iraklis, coming as a substitute for Paulo Costa in the 46th minute. Levadiakos was relegated in the Football League for the following 2010-2011 season and the club"s youngsters, including Machairas, were expected to play a major role in the club"s fight for a Superleague return.
Sure enough, Machairas made 18 appearances for Levadiakos in the 2010-2011 Football League, a season which saw Levadiakos being promoted to the Superleague despite losing the promotion play-offs, thanks to the Koriopolis scandal.
Machairas was called up at the Greek national under-21 football team in May 2012 for a 2013 Union of European Football Associations European Under-21 Football Championship qualification match against San Marino but stayed on the bench.
