And now reports suggest the east London side are prepared to let Hernandez go in the January transfer window - but who are the favourites to sign him? Sources close to Hernandez have confirmed that whilst the player is happy at West Ham - he does not like the idea of spending too much time on the bench, so would accept a move away from the club and accepts that means a likely move overseas.
Chicharito cost the club just £16m from Bayer Leverkusen and many tipped him to become one of the signings of the season, but things simply haven't gone to plan.
The former Marseille man has struggled so far this season scoring only 3 goals in his 17 league appearances.
If West Ham can't find a buying club willing to pay a suitable price for Hernandez and offer him a salary he'd accept, he faces the prospect of rotting on the bench in the coming months.More news: Brightline Train Makes Ft. Lauderdale, West Palm Beach Inaugural Run

Moyes is also reportedly close to cashing in on another striker in Diafra Sakho - the Senegal global is apparently on the verge of joining Crystal Palace.
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.
Moyes now intends to reconfigure his attack around other players and offload Hernandez, who earns around £130,000-a-week ($9.1 million per year) and is West Ham's highest-paid player.
