The new Hammers boss had a furious bust-up with Morgan Amalfitano, with the Frenchman’s future now in doubt, according to the Mirror.
As such, Amalfitano has paid the price for challenging Slaven Bilic’s authority by being axed from the first team-fold and ordered to train with the Hammers' youth team.
Reports suggest that the duo clashed after the Frenchman missed a team meeting.
The Frenchman is believed to have “given the manager attitude” when he took exception to being confronted about his absence in front of his fellow teammates.
Bilic arrived at West Ham with a reputation for taking a no-nonsense approach with his players, and it was seemingly only a matter of time until we witnessed the effects of the Croatian's managerial approach.
However, this is not a one time occurrence for Amalfitano at Upton Park.
In 2014, the Frenchman was branded “unprofessional” and disciplined by then-boss Sam Allardyce after being shown a straight red card in just nine minutes on the pitch as a substitute in the club's FA Cup defeat at West Brom.
The 30-year-old made 24 appearances - 14 starts - for the Hammers last season, scoring three goals in total.
He ended the season having completed just 79% of his total attempted passes and 45% of his take ons, while fashioning 10 chances for his team-mates in the final third.
