Jason Demetriou (; born 18 November 1987) is a Cypriot international footballer who last played as a defender for club Southend United. In October 2021, Demetriou also took temporary charge of the Southend first team as interim head coach.
Demetriou came through the youth ranks at English club Leyton Orient and signed his first full professional contract with the team in July 2006. He made his league debut in November 2006 when he came off the bench in a 0âÂÂ0 draw with Yeovil Town. He went on to make 24 appearances in his first year, in both league and cup competitions, mostly as a substitute.
The 2007âÂÂ08 season was a breakthrough season winning the young talent award for Leyton Orient. Demetriou himself has given much credit to ex-manager Martin Ling for giving him the chance to prove himself at this level of football particularly in the 2007âÂÂ08 season.
Despite Leyton Orient struggling throughout the 2008âÂÂ09 season, Demetriou's performances impressed the fans and he was linked with big money moves away to Premiership and Championship clubs Plymouth Argyle and Charlton Athletic. The Orient play-maker publicly stated his intent to stay at Brisbane Road and, at the end of the season, was awarded the Fans' Player of the Year award.
Demetriou officially signed for AEK Larnaca on 2 June 2010, for an undisclosed fee, to be able to progress as an international for Cyprus. He said he was very sad to leave Leyton Orient but had to move in order to play international football.
On 28 June 2013, Demetriou signed a three-year contract with Anorthosis Famagusta. On 31 August 2013, scored on his Anorthosis Famagusta debut, in a 3âÂÂ1 win against Omonia.
On 1 July 2015, it was confirmed that Demetriou had signed a contract for Walsall for an undisclosed fee, pending international clearance.
On 22 June 2016, it was announced Demetriou had signed for Southend United, subject to a medical being completed. Demetriou had turned down a new deal at Walsall and also the chance to move to Portsmouth. In October 2021, Demetriou took charge of the first team as interim head coach following the sacking of Phil Brown as manager, winning his only game in charge, a 4âÂÂ1 win over Chertsey Town in the FA Cup fourth qualifying round on 16 October 2021.
Prior to the 2023âÂÂ24 season, Demetriou joined Kevin Maher's coaching staff at Southend.
On 30 August 2024, after 260 appearances in all competitions, Demetriou announced he had left Southend United. One month after leaving Demetriou was announced as Southend's new chief scout.
On 20 January 2009, he was called up to Cyprus squad for the first time by manager Angelos Anastasiadis, qualifying thanks to his Greek Cypriot paternal roots. He made his debut against Serbia in the 2âÂÂ0 home defeat coming on as a sub for Demetris Christofi on 10 February. On 11 February Demetriou made his second appearance and full debut against Slovakia, where he assisted two goals in a 3âÂÂ2 win for Cyprus. He was awarded man of the match award for his performance in this match. On 10 October 2015, he scored his first international goal, netting the winner in the 1âÂÂ2 away win for Cyprus against Israel in the UEFA Euro 2016 qualification stage, which allowed Wales to qualify for UEFA Euro 2016 despite losing to Bosnia and Herzegovina. Demetriou retired from international football in 2020.
