Tasos Avlonitis

Avlonitis started as an amateur in his hometown team Chalkineo Evias in which he played in the local league. In 2007, he was signed to Egaleo, which for three seasons played in Football League. In the 2008–09 season he was loaned to Ilisiakos. In 2010, he signed to Kavala, where he played the 2010–11 season. After the involvement of the club President Psomiadis in a match-fixing scandal, Avlonitis was released and signed a contract with Panionios.[1]

In July 2014, Olympiacos announced the transfer of Avlonitis from former club Panionios for a fee of around €670,000. On his first derby game against Panathinaikos, on 26 October 2014, Avlonitis scored the winning goal for Olympiacos, as they beat Panathinaikos 1–0 at home. His next goal came against Panthrakikos in a 5–1 home win. On 30 January 2015, the Austrian club Sturm Graz have expressed an interest to sign Olympiacos defender on loan. The Greek defender is not in Marco Silva's plans and Sturm Graz are moving towards to clinch a loan deal until the end of the season.[2] Eventually, the central defender will continue his career in Austria for Sturm Graz, on loan until the end of 2015–16 season.[3] On 6 February 2016, he made his debut with the club in a 2–2 away draw against Altach.

On 1 September 2016, he mutually solved his contract with Olympiacos.[4]

On 30 January 2017, Avlonitis signed for Scottish Premiership club, Heart of Midlothian on a six-month deal running until the end of the 2016–17 season.[5] On 22 May 2017, Avlonitis was released by the club, following the end of the Premiership season.[6][7]

On 11 September 2017, Avlonitis signed a two years contract with Superleague club Panathinaikos for an undisclosed fee.[8] In the first half of the 2016–17 season, the central defender was bright in for defensive cover and has found first team minutes hard to come by since arriving but when called upon he has demonstrated he can be trusted. Given his lack of playing time it is hard to judge but he is expected to feature more often in the second half of the season after the probable departure of Rodrigo Moledo.

In April 2018, Avlonitis signed a two-year contract with his former club Sturm Graz, in which he played on loan from Olympiacos on the second half of the 2015–16 season. He had previously terminated his contract with Panathinaikos at his own request.[9] On 9 August 2018, he played his first international game as a starter in a 2–0 home loss for UEFA Europa League Third qualifying round, 1st leg game against AEK Larnaca. On 21 September 2019, he scored his first goal with the club with a kick after a Kiril Despodov's corner in an away 3–3 draw against SV Mattersburg. The Greek defender, who has been irreplaceable this season in Sturm Graz's backline, produced a cheeky back-heel assist to register his second assist of the season. As a result of his excellent form, was included in the Best XI for matchday 18 in the Austrian Football Bundesliga.[10][11] On 28 December 2019, Sturm Graz revealed their Team of the Decade, with Avlonitis and Charalampos Lykogiannis both included in the starting 11.[12]
