The Montenegro player is reported to be one of the highest-paid Academy players rumoured to be earning £15,000 per week breaking the upper pay structure of the youth setup.
Football agent Will Salthouse is said to have been involved in the double deal that bought both Arnautiovic and Haksabanovic to West Ham and it is claimed that both players were required to be signed to sign Arnauotvic.
Early indications from training ground staff after his arrival were that Haksabanovic was unlikely to make the Premier League grade needed for the first team and the player was sent out to Malaga then Norrköping to help cut some of the Hammers losses.
