The Hammers could bring in the proven Mexican international, who has an impressive record of 40 goals in 74 international caps, as a replacement for Enner Valencia, who picked up a potentially lengthy injury this week, while another key front-man Andy Carroll is also known for spending a great deal more time on the treatment table than on the pitch.
Although Hernandez has not been at his best in the last couple of years, scoring only 18 goals in all competitions in the last two seasons, his scoring record in limited playing time suggests he could definitely have something to offer a club like West Ham.
The 27-year-old was considered something of a hit when he first moved to United back in 2010, scoring 20 goals in all competitions in his debut campaign to help fire the Red Devils to the Premier League title.

However, he has failed to build on that after becoming less of a regular in the side, which became even harder when big names like Robin van Persie were brought in, as well as Radamel Falcao on loan last summer, which in turn saw Hernandez loaned out to Real Madrid.
Chances were also few and far between at the Bernabeu due to the presence of big names like Cristiano Ronaldo, Gareth Bale and Karim Benzema in the Spanish giants’ attack, but he still managed 9 goals in total, including a crucial late winner against Atletico Madrid in the quarter-finals of the Champions League.
Still, the Standard claims that West Ham have failed with a £9m bid and that Reds boss Louis van Gaal wants to keep the player at Old Trafford for the time being, possibly due to a lack of other backup options and no new signings up front so far this summer.
