Hernandez has been tracked by some of America's leading clubs, who are said to be prepared to offer him a big wage rise, but the Mexican striker wants to stay in Europe.
The 26-year-old feels that he still has a lot to offer in a league of a higher standard than MLS and it means that West Ham and Southampton could be amongst the leading contenders to sign him this summer.
It is believed that Hernandez has already been informed that he is surplus to requirements at United and both Southampton and West Ham are expected to lodge bids in the summer.
It will then be up to the pair to fight it out for his signature and his arrival could be crucial for either of the Premier League's sides' seasons.
Hernandez has the potential to enhance Southampton's attack considerably. At the moment the Saints have Graziano Pelle at their disposal, but they lack a clinical finisher beyond him and will need to add competition in the summer.
West Ham, meanwhile, have more attacking options, but they do not have anyone as proven as Hernandez.
Although the United man has not found form for the past few seasons, he has already shown his lethal finishing ability in England and that could make the difference as the Hammers look to mount a European challenge next year.
