The 28-year-old is set to become the Hammers second summer signing, following Pablo Zabaleta to the London Stadium as the club finally make another move in the transfer market.
With Arnautovic seemingly destined for the London Stadium, we spoke to Martin Spins from our sister title the Stoke Sentinel to give us his expert view as someone who watches the Austrian week in, week out.
He explained that the Hammers will be getting someone who is a bit moody but who will be a massive miss for the Potteries.
West Ham need a striker. Is Arnautovic the player that can fill the void or is he more of a winger?
He is definitely a winger by trade but does have the physical power to play up front or behind the main striker, now and then at least. He certainly knows where the goal is on his day.
Mark Hughes has said Arnautovic won’t be sold. Do you think they will keep hold of him?
It’s definitely late in the day to start looking for a replacement for one of your main men and he hasn’t previously given much indication of being restless or unhappy, mind you he always looks miserable so it can be difficult to tell with him.
What are Arnautovic’s strengths?
That power mentioned above, along with a fair turn of pace and an ability to time runs inside on the diagonal to pick up a half decent through ball, while his shooting can be explosive on his day.
Also, his weaknesses?
He can switch off defensively and leave his full back outnumbered, while his chin can easily drop in adversity and he can go missing when demotivated.
Motivation at Stoke could be a problem for him going forward, particularly after declaring his hand now, so this is one argument for cashing in now if the offer was good enough and a decent replacement can be lined up.
Would Stoke fans be disappointed to see him go?
Yes. Last summer we were all resigned to losing him and then he signed a long-term contract when no-one came in for him. Losing him then would have been a bigger blow than now because 15/16 was his best season and 16/17 was pretty average by comparison.
But if he was sold now and not adequately replaced, that would presumably leave fans concerned about the attacking strength of the team and the club’s ambition.
