The Hammers chose to sack Slaven Bilic on Monday, less than 48 hours after the 4-1 home thumping at the hands of Liverpool last weekend – and they didn't waste any time in replacing him.
David Moyes arrived as West Ham's new manager on Tuesday, and the Scot will have the international break to get to know his players before his first game against Watford a week on Sunday.
Long-term, Moyes will be hoping to bring in new faces in January, but in order to do that, he may need to offload some players – and The Mirror report that he has been given the green light to sell any player he wants, despite only having a contract until the end of the season.
One player allegedly primed for the chopping block already is forward Marko Arnautovic, even though the Austrian international only joined the club from Stoke City over the summer.
The 28-year-old completed a club-record move to the London Stadium after four years with Stoke, where he hit 26 goals in 145 games before heading to West Ham – where he has failed to impress.
Arnautovic has yet to register a goal or an assist for West Ham, turning in disappointing performances and even picking up a red card in just his second game of the season, with fans far from impressed so far.
The former Inter Milan and Werder Bremen ace has often been criticised for his application and effort, and with Moyes desperate to get his players working hard, Arnautovic is allegedly in danger of being sold in January – but the Hammers may struggle to recoup their outlay.
