Upton Park side look to bring in Old Trafford marksman.
Hammers boss Slaven Bilic has made QPR ace Charlie Austin his first choice option in this regard but could be scared off by the 25-year-old’s £15m valuation.
Man United are likely to offload Hernandez this summer and could accept an offer less than the amount QPR want for Austin and the Mexican international is certainly a proven Premier League goal-scorer.
Chicharito has bagged 37 goals in 102 Premier League appearances, of which 53 were from the bench, and when called upon during his loan spell at Real Madrid in 2014/15 the 27-year-old was not found wanting.
Louis van Gaal is keen to clear the Old Trafford decks of players he deems surplus to requirements and has already sold Tom Cleverley, Nani and Robin van Persie.
