As things stand Hernandez doesn't look likely to improve any time soon as a West Ham player, with Moyes opting to move the rejuvenated Marko Arnautovic into a striking position alongside Carroll or Michail Antonio, meaning even less chance for him to build up any consistency.
Effect of his form, Sky Sports reported that West Ham are willing to listen to offers for the former Manchester United and Real Madrid striker. The rumor emerges just five-plus months after Hernandez joined West Ham from German club Bayer Leverkusen in a £16 million ($21.6 million) transfer, and he might be on the move again ahead of the 2018 FIFA World Cup.
In 17 league appearances this season, the Mexican has managed just four goals and has struggled to get back to grips with Premier League football.
Hernandez's form in his second spell in England has been somewhat surprising given the 29-year-old's stunning arrival on the European scene at Manchester United.
BOURNEMOUTH have told West Ham that they must cough up £15million to land Republic of Ireland star Harry Arter.
Hernandez, who is West Ham's top earner, may be concerned his poor season will impede on his hopes of remaining a regular for Mexico ahead of this summer's World Cup in Russian Federation.
