West Ham are a much better team when Marko Arnautovic leads the line.
Arnautovic is the talisman of the team and his presence up front seems to lift the other players to match his level of performance.
The Austria international was a wanted man in the summer, with Manchester United linked.
This interest is bound to resurface when the January transfer window re-opens, especially if he keeps up his form.
But West Ham need to ensure Arnautovic does not leave. This is central to their chances of success this season.
Arnautovic at West Ham
Arnautovic has been a revelation for West Ham ever since David Moyes came in last year.
The 29-year-old has moved into a central striker position and that has paid dividends, with goals, assists and dominant displays coming each week.
This season, Arnie has four goals in six Premier League games and is towards the top of the list in the race for the golden boot.
Key to success
Whatever West Ham deem a successful season will depend on their start to the year.
By January, we should be able to gauge whether West Ham are battling relegation, pushing for Europe and still in with a shout of winning silverware.
No matter what the aim is for the Hammers, Arnautovic needs to be a central part of their plans.
Without him, West Ham are simply not as good. They need the powerful Austrian’s goals and all-round game play to achieve their targets.
West Ham must resist any bids for Arnautovic in the January window. The Irons should not sell for £50m and I cannot see any team wanting to spend more than that on this player.
