Stoke forward Marko Arnautovic has handed in a transfer request, according to multiple reports.
The 28-year-old has asked to leave the bet365 Stadium amid reported interest from West Ham, who Sky Sports said had a bid of £15m turned down by Stoke.
Arnautovic, who only signed a new four-year deal at Stoke last summer, is currently with the squad in Switzerland for their preseason training camp.
Stoke reportedly have made no decision over the request and Arnautovic is due to play against Neuchatel Xamax on Monday as the Potters kick off their preseason programme.
The Austria international was linked with Everton last year before signing his new deal and Stoke would be unwilling to have another transfer saga.
