Kostas Fortounis

He netted twice (one penalty) helping his club to reach a 3–1 home win against his former club Asteras Tripoli on 29 November; it was the 11th win in a row for the club equalling the club record from the 1966–67 season.

On 5 December, he scored a penalty in a 4–3 away win against Panthrakikos.

Fortounis missed a penalty before making an assist in the 90th minute to secure a 2–1 victory over 10-man Dinamo Zagreb in the Champions League in November.

Konstantinos 'Kostas' Fortounis (, ; born 16 October 1992) is a Greek professional footballer who plays as an attacking midfielder for Super League club Olympiacos for which he is the club captain as of October 2023.

He was born in Trikala, Thessaly but comes from the nearby village of Sarakina, close to the town of Kalabaka.

On 20 March, Fortounis became the third player in Olympiacos' history to score 10 goals and make 10 assists in a season (after Predrag Đorđević in 2001–02, 2002–03 and 2003–04, and Chori Dominguez in 2014–15).

After leaving Olympiacos' youth team in 2008, Fortounis moved to Trikala to play for AO Trikala.

After an impressive spell in the Under-21 side scoring four goals in 14 matches, he began his career with the first team in the fourth division, where from 2008 to 2010 he played in 13 matches and scored 1 goal.

Because of his good appearances with the Greece under-17 national team, Vangelis Vlachos, Asteras Tripolis' manager convinced him to join the Peloponeesean team.

He made his debut in a draw with PAOK in Tripolis.

Used predominantly as a substitute, the teenager clocked up 24 league appearances, scoring his first Super League goal on 19 September 2010 in a 2–2 draw at AEK Athens, unable, however, to save the side from relegation.

Due to his good performances at Asteras, Juventus made an offer in the winter transfer window for a loan transfer until summer with an option to buy him.

Asteras finally declined Juventus's offer.

In the 2011 summer transfer window, Fortounis moved to Kaiserslautern on a contract until June 2015 after being transferred for an undisclosed fee.

In his first season with the club, the midfielder made 28 league appearances but endured a second successive relegation.

He reportedly attracted interest from Dutch champions Ajax and Italian champions Juventus midway through the season.

In the 2012–13 season he scored twice in 24 appearances as he helped Kaiserslautern to a third-place finish in the German second tier only to miss out on promotion due to defeat in the promotion/relegation play-off with Hoffenheim.

On 16 April 2014, he missed his first final of his career in the semifinal of DFB-Pokal by facing as a substitute a 5–1 loss from the German champions Bayern Munich.

On 21 July 2014, Fortounis signed a five-year contract with Olympiacos, returning after six years.

He said he chose the club ahead of PAOK and Panathinaikos because they could offer him Champions League football, but was left out of the squad for that competition.

He scored his first goal for Olympiacos in the Superleague match against PAS Giannina on 6 December, a penalty kick in a 2–2 draw, and went on to score 7 goals from 25 appearances in the 2014–15 Superleague.

Fortounis helped Olympiacos reach the 2015 Cup Final, in which he scored the third goal with a 25 yards free kick as they beat Skoda Xanthi 3–1 to complete the double with a record 27th cup win.

Fortounis scored Olympiacos' first goal of the 2015–16 Superleague season in a 3–0 win over Panionios.

In the second match of the season, against Levadiakos, he secured the victory by scoring the second goal in stoppage time and was named "Man of the Match".

On 22 September 2015, he scored twice in Olympiacos's 3–1 defeat of Skoda Xanthi and assisted Jimmy Durmaz for the opening goal.

He was again named "Man of the Match".

He scored for the second league match running against PAS Giannina in a 5–1 home win.

On 29 September, away to Arsenal in the Champions League group stage, he was involved in Felipe Pardo's opening goal and his corner led to goalkeeper David Ospina fumbling the ball over the goalline to give Olympiacos a 2–1 lead, a performance that earned him a spot in the Champions League Team of the Week.

On the seventh matchday of the Superleague he scored two goals in a 4–0 home win against AEK after being brought onto the pitch in the second half.

Two weeks later Fortounis converted two penalties in a 2–0 victory against Kalloni, their 15th win of the first half of the season during which they remained unbeaten.

He scored his first goal in European competition on 25 February with a penalty kick in a 2–1 home defeat to Anderlecht that eliminated Olympiacos from the 2015–16 Europa League at the round of 32 stage.

On 31 January 2016, he scored a brace and assisted once in his club's 3–0 win over PAS Giannina at Zosimades Stadium.

He scored his first goal of the 2016–17 season on 2 October 2016 in the 3–0 home derby win against AEK.

On 24 November 2016, in a UEFA Europa League group stage he scored from a free-kick to open scoring in a final 1–1 home draw against BSC Young Boys and was chosen MVP of the match.

On 28 February 2017, he helped his club, as a substitute, to escape with a vital 2–1 away win for the quarter-finals of Greek Cup, against Atromitos by equalizing the score and giving the assist for the winning goal.

On 5 April 2017, he opened the score in a crucial 2–0 away win against Kerkyra, helping his club in their effort to win the 7th consecutive championship.

He finished the season with 40 appearances (8 goals, 8 assists) in all competitions.

Fortounis scored twice in a 4–1 home win against AEL on the opening day of the 2017–18 Superleague season, and the following week scored the only goal of the visit to Lamia from the penalty spot.

In the final match of the Superleague season, Fortounis scored his 18th goal, which made him the league's top scorer by a three-goal margin; he was also the top assister with 12, as his team won their sixth consecutive title.

Despite interest from clubs including Bayer Leverkusen and Tottenham Hotspur, Fortounis' contract with Olympiacos was extended to 2020.
