Marko Arnautovic has left Stoke City for West Ham United in the summer transfer window.
Arnautovic, who can operate as a forward or as a winger, has left Stoke for Premier League rivals West Ham in the summer transfer window.
According to BBC Sport, the Hammers have paid the Potters a transfer fee of £20 million which could rise to £25m in order to secure the services of the Austria international attacker.
Stoke midfielder Adam, who is 31 years of age, has stated that Arnautovic will have to improve his game in order to be a success at the London Stadium.

“He will need to improve because he’s going to be the record signing, and the West Ham fans, they won’t take anything,” Adam told talkSPORT about Arnautovic. “
They won’t take him not tracking back, covering the full-back, helping his own full-back – they will be on him so he’ll have to improve.
“Maybe at our place he can get away with it a little bit because going forward he’s a match winner and coming to a team like West Ham they need someone like that.
“He’s got the talent to go play for one of the big ones but he’s going to West Ham because sometimes going back the way he doesn’t do as well as he should do.”

Arnautovic is a good attacking player and has a lot of experience in the Premier League, but the Austrian does need to be more consistent.
The 28-year-old former FC Twente and Werder Bremen man scored six goals and provided five assists in 32 Premier League appearances for Stoke during the 2016-17 campaign.
