Sky Sports claims the Hammers were in talks with the striker having activated his paltry - by today's standards - £13.5m release fee at Bayer Leverkusen.
That has infuriated fans who have watched the club fail time and again to make good on promises over transfers in the last 18 months.
Slaven Bilic has targeted four "game-changer" signings this summer which includes two new strikers with a priority on pace and proven goalscoring ability.
Javier Hernandez in action
Supporters feel given the relatively low transfer fee the club should have no problem matching the Mexican's wages, especially given the fact former hero Dimitri Payet was on around £125,000 per week after signing an improved deal.
The focus this summer has been on shifting the deadwood for West Ham with the likes of Alvaro Arbeloa, Gokhan Tore, Havard Nordtveit, Enner Valencia, Stephen Hendrie and Raphael Spiegel following Payet and Simone Zaza out the door.
The likes of Robert Snodgrass, Andre Ayew and Sofiane Feghouli could follow them out the exit door too as Bilic tries to clear the decks.
Hammers fans were shocked to learn this week that winger Feghouli - who was signed on a free transfer from Valencia last summer - was the club's second highest earner - as claimed by well-placed West Ham source ExWHUEmployee on the West Ham Way radio show.
The Algerian international has been linked with a £4.5m move to Turkish giants Galatasaray, as reported by The Sun.
So could getting him off the wage bill be the key to pushing a deal for Hernandez over the line?
Sofiane Feghouli has struggled to make an impact under Slaven Bilic
Andy Carroll is reportedly on £90,000 per week at West Ham and Jose Fonte and Robert Snodgrass are believed to be among the top earners since arriving in January.
So it is fair to say Feghouli's wages sit between the £60-80k mark, making the club's desperation to offload him all the more acute.
That won't wash for some supporters, though, who feel the club should be able to afford it regardless after being promised the move to the Olympic Stadium - and the increased TV, merchandising and ticket revenue - would allow the club to compete for top players in the transfer market.
