AC Omonia participant of 2013–14 Cypriot First Division
Financial crisis (2012–2018)
Head coach Neophytos Larkou left the club in September 2012 and Toni Savevski was then appointed as coach. The team began the season with a great win but found its second success after several games. A disappointing first round proved enough to exclude the club from contesting for the championship or the cup. The team managed better results in the second round, finishing the season in third place. Thousands of fans answered the president's call to donate as much as they could and the financial issues of the club improved. Omonia was knocked out in the semi-finals of the cup by AEL Limassol.
In 2013, Omonia began the new season with Savevski as manager, but he was sacked halfway beside positive results. Miguel Ángel Lotina was hired as the replacer, but was sacked just 37 days later. Kostas Kaiafas, ex-player was then appointed as the new coach. The club's financial difficulties returned despite the massive fundraiser organized the previous season. Omonia finished fifth in the league, making it its worst season in 56 years.In August 2014, Omonia was knocked out of the Europa League by Dynamo Moscow, in the play-off round. The club issued a complaint to UEFA regarding the refereeing of the match by Alexandru Tudor. In early September, the club stopped supplying the fans' group Gate 9 with tickets resulting in the group's abstention from matches. Two weeks later, after a meeting between the president and the coach, it was decided that tickets were to be supplied again to Gate 9. Omonia finished fourth in the league. The team was eliminated from the Cypriot Cup in the semi-finals by APOEL.The team ended the 2015–16 campaign in 4th place. During this season, Omonia reached the final of the Cypriot Cup but lost to Apollon Limassol. The 2016–17 season saw the club finish 5th. This meant that for the first time in 15 years the club had failed to qualify for European football. Following a general assembly at the end of the season, Antonis Tzionis was elected as the new club president. While the 2017–18 campaign began with high expectations, Omonia finished the season in 6th place. This season was the worst in the club's history, in terms of defeats and goals conceded. Despite this, the club sold a total of 95,222 tickets during the season, more than any other team in the league.
