There were plenty of theories surrounding what Haller was filming.
Watch one of the best freestylers in the world attempt some of football’s hardest skills with fruit in the video below…
A number of fans thought he was recording an announcement stating that he will be the Hammers’ new number nine, while another speculated that he was taking part in an announcement video for another new striker.
However, none of these theories have proven to be correct as the striker revealed that he is going to be starring in a new web-series on the French platform CANAL+.
The series will follow the former Frankfurt striker’s life in the Premier League, and the 25-year-old shared a teaser trailer on his Twitter account.
As you can see, the same shot from his Instagram post is used in this teaser trailer – putting to bed the mystery of what his snap was about earlier this month.
