Marko Arnautovic joined his West Ham United teammates for the start of the second week of pre-season training in Switzerland on Tuesday.
The 2017/18 Hammer of the Year was put through his paces for the first time under new manager Manuel Pellegrini, having been given an extra week off after participating in international friendlies with Austria at the end of last season.
