Arsenal won the trophy for the 14th time. Papastathopoulos and Mesut Özil were notably excluded from Arsenal's Premier League and Europa League squads for 2020–21, leaving them only eligible for one League Cup game between October and January. On 20 January 2021, Arsenal announced that Papastathopoulos would be leaving the club after his contract was canceled "by mutual consent." Olympiacos On 25 January 2021, Papastathopoulos joined Greek side Olympiacos on a two-and-a-half-year contract. On 21 April 2021, he scored his first goal with the club, in a 1–0 home win game against Asteras Tripolis. International career Papastathopoulos was called up for the Greek senior team on 1 February 2008 and made his debut on 5 February 2008 in the 1–0 friendly victory against the Czech Republic. The Greece squad for UEFA Euro 2008 was announced by Otto Rehhagel on 27 May 2008, and Papastathopoulos was the unfortunate player to be cut from the provisional squad of 24 to the final 23-man selection. Papastathopoulos became the first player to be sent off at UEFA Euro 2012 during the opening game of the tournament against co-hosts Poland after receiving two yellow cards, following what pundits decried as two poor decisions by referee Carlos Velasco Carballo. In June 2014, Papastathopoulos was named to the Greece national team for the 2014 FIFA World Cup. He started in each of the team's group matches, helping them to a clean sheet against Japan. In the round of 16, Papastathopoulos scored his first international goal, equalising in second half stoppage time against Costa Rica. However, the Greeks were eventually defeated 5–3 in a penalty shoot-out by the Central American champions. On 11 June 2019, following the loss to Armenia at the Olympic Stadium, Papastathopoulos called for immediate changes to be made to the Greece national squad set-up, and he allegedly requested for Angelos Anastasiadis to be removed from his role of head coach when speaking to EPO president, Evangelos Grammenos. Personal life Papastathopoulos was born in Kalamata, Peloponnese. He married Xanthippi Stamoulaki in 2014. Together they have three children.
