Marko Arnautovic has left Stoke City for West Ham United in the summer transfer window.
Stoke City forward Bojan Krkic has taken to social networking site Twitter to send a message to new West Ham United signing Marko Arnautovic.
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 forward Krkic, who is 26 years of age and can also operate as a winger, has taken to Twitter to send a message to the 28-year-old former FC Twente and Werder Bremen man.


Arnautovic is a good attacking player and has a lot of experience in the Premier League, having been on the books of Stoke since 2013.
The forward, though, can be inconsistent, but he is at his peak and could make an instant impact for West Ham.
The Hammers endured a disappointing 2016-17 campaign and will be aiming to break into the top eight of the Premier League next season.
