In November, new manager David Moyes said that Arnautović had to work harder and be more of a team player or be dropped. 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. He followed this with a goal in his first return to the Bet365 Stadium in a 0–3 win against Stoke City on 16 December. Following his conversion from a winger to a centre-forward at West Ham, Arnautović scored 11 Premier League goals in his first season at the club; his goal against Everton on the final day of the campaign making him the first West Ham player to reach that figure since Bobby Zamora in 2006–07. In April 2018, he was named as Hammer of the Year for the 2017–18 season.
