Marko Arnautović (Serbian Cyrillic: Марко Арнаутовић; born 19 April 1989) is an Austrian professional footballer who plays as a forward for Serie A club Inter Milan, and vice-captains the Austria national team.

He impressed at De Grolsch Veste and after a fine 2008–09 season he joined Italian giants Inter Milan on loan, where he made only three appearances due to injury.

He joined West Ham United in July 2017 for a fee of £20 million and won the Hammer of the Year award in his debut season.

A full international with 120 caps for Austria since 2008,[2] Arnautović is the most-capped and second-highest scoring player in the history of the national team, behind Toni Polster.

[12] Arnautović made his professional debut for FC Twente in the 2006–07 season as a substitute for Kennedy Bakircioglu against PSV Eindhoven in April 2007.

In the 2008–09 season Arnautović scored 14 goals in 41 matches as Twente finished 2nd in the Eredivisie and reached the knock out phase of the UEFA Cup.

[14] In March 2009 after a league match against Willem II, one of Twente opponents, Ibrahim Kargbo, accused Arnautović of racially abusing him.

[17] He made his unofficial debut for Inter in a friendly match on 5 September 2009 against Swiss team, Lugano, the final score was 3–3.

At the end of the season Inter decided against turning his loan into a permanent move with manager José Mourinho stating that Arnautović "is a fantastic person but has the attitude of a child".

[citation needed] In March 2012, he was ruled out for two months with a knee ligament injury he suffered whilst playing with his dog.

[43] He scored once in 29 league appearances over the campaign: a 95th-minute equaliser against West Ham United on 11 April 2015, having earlier in the match had two goals disallowed for offside.

[45] Arnautović's first appearance of the 2015–16 season came in a 2–2 draw with Tottenham Hotspur at White Hart Lane on 15 August, scoring the team's first goal as they came back from 2–0 down.

[48] On 28 December, Arnautović won a last-minute penalty kick against Everton at Goodison Park when he was fouled by John Stones, and sent it past goalkeeper Tim Howard to win the match 4–3.

[49] He scored the only goal of the League Cup semi-final second leg against Liverpool on 26 January 2016, forcing a penalty shootout which his team eventually lost.

[61] He scored his first goal for the club on 9 December, the only one of a win over reigning champions Chelsea at the London Stadium, in what was Moyes' first victory as West Ham manager.

[67] In January 2019, he was the subject of a £35 million transfer offer from a Chinese club, believed to be Shanghai SIPG, which his agent and brother, Danijel, said Arnautović wanted West Ham to accept.

[75] On 15 August, Arnautović made his debut for Bologna, in a 5–4 defeat against Ternana in the first round of the Coppa Italia, scoring a goal in the 56th minute.

[81] Arnautović played with the Austrian under-19 side in the 2007 UEFA European Under-19 Championship where he was sent-off in their second match and failed to make it out of the group stage.

[82] After scoring a free-kick in an under-21 game against Denmark in March 2010, Arnautović earned praise from manager Andreas Herzog who described him as the best Austrian footballer of the last 30 years.

[84] Arnautović started in all ten of Austria's matches during their successful UEFA Euro 2016 qualifying campaign, scoring in a win over Montenegro and both fixtures against neighbours Liechtenstein.

[86] Arnautović started all but one of Austria's qualification matches for the 2018 FIFA World Cup, only missing the game against the Republic of Ireland through suspension.

[90] During the goal celebration, he was accused of using racist slurs against Ezgjan Alioski and Egzon Bejtulai from the rival team, who are both Macedonian Albanians.

[96] Later that year, on 25 September, he became the most-capped Austrian player with 104 caps, breaking previous record of Andreas Herzog, in a 3–1 home defeat against Croatia during the same tournament.

[104] A versatile forward, Arnautović has played in several offensive positions: for the majority of his career, he served as a winger; however, during the 2017–18 season,[105] his West Ham manager David Moyes made the decision to transition the Austrian effectively into a striker or a centre-forward, in order to utilise his physical and technical abilities in central areas of the pitch.
