David Moyes' future as West Ham manager is in fresh doubt, talkSPORT understands.

Moyes was close to agreeing a new two-and-a-half year contract in December following their historic Europa Conference League victory last term.

However owner David Sullivan is now less certain about keeping the Scottish boss beyond the end of the season.

The east Londoners are currently on a seven-match winless run in all competitions with Sunday's 6-0 thrashing by Arsenal their heaviest-ever home Premier League defeat.

Sullivan is also said to be concerned by a growing negativity towards Moyes from Hammers fans.

That said, it's understood that Moyes will be given time to reverse West Ham's fortunes.

The club's next four games will go a long way in deciding his fate with those fixtures all against teams in the bottom seven in the Premier League table.

They includes fixtures against Nottingham Forest, Brentford, Everton and Burnley.

Moyes also has credit in the bank with Sullivan after last season's European heroics, with success in the Europa Conference League being the first major trophy that the club have won since 1980.

The 60-year-old is currently in his second spell as West Ham boss having previously managed the club from 2017 to 2018, before rejoining in 2019.
