"Everyone knows that West Ham is a big club, with big history, and I'm happy to be a part of it now," Arnautovic told the club website after leaving Stoke, where he played for four seasons, scoring 22 Premier League goals. "The club is still growing, getting better and better, and that's why I'm here," he added. The fee, which West Ham confirmed was a club record, was reported by British media to be up to 25 million pounds ($32.48 million), exceeding the 20.5 million pounds the club paid Swansea for Andre Ayew in 2016.

Joint-chairman David Sullivan told the club website: "Alongside Pablo Zabaleta and Joe Hart, we have brought in three players with vast Premier League experience this summer, and that was one of our key targets." Arnautovic, who previously played for FC Twente and Werder Bremen, has played 62 times for his country, scoring 15 goals.
