The Sebastien Haller situation at West Ham United is not only causing a divide but undoubtedly giving David Moyes sleepless nights.
Haller completely polarises the West Ham fanbase.
Many think he is lazy and will simply never be able to justify his record £45million price tag.
Others believe the Frenchman has been misused ever since signing for the Hammers last summer.
Same old debate as Haller gets his chance
With Michail Antonio injured Haller came into the side for the defeat at Liverpool.
But it was the same old story. Pilloried by some West Ham fans – and pundit Jamie Carragher – for a lack of effort, Haller barely had a kick before being substituted in the second half.
He looks likely to get another chance against Fulham this Saturday night.
Haller will only win over a section of the fanbase if he ups his workrate. Indeed with Antonio as a benchmark it is a tough act to follow in that respect.
Up to Moyes to find a solution
But the reality is that Moyes holds the key as he must find a way to get the best out of his expensive striker if he continues to use him in the side.
Some fans believe he must be played as part of a two-man strike partnership.
Others feel reverting to a back four to get two wide forwards up alongside him would work too.
It may be a different team, different level of opposition and a different league, but a video of Haller’s time at Eintracht Frankfurt could well provide Moyes with the answers to solving the Haller riddle.
The Bundesliga posted a video on YouTube before his move to West Ham last summer titled ‘Sebastien Haller – Bundesliga’s best’.

The video charts ‘Haller’s path to becoming one of Europe’s best strikers’.
And Moyes should watch the eight-minute narrated video for some key insight into how to unlock Haller’s potential.
Particularly from around 4mins 40secs.
One of the criticisms of Haller is his lack of emotion when playing for the Hammers.
But interestingly the video remarks how Haller has always showed little emotion on the pitch.
Indeed the striker himself appears on the video explaining that he prefers to stay ‘calm and cool’ and that only his daughter has made him emotional.
Now it is over to Moyes to solve the puzzle which could dictate how well West Ham do this season.
