Having lost Carlos Bacca to AC Milan a fortnight ago in a £21million deal, the Europa League winners' head coach Unai Emery is targeting a cut-price move for the Mexican international's services.
The 27-year-old spent the previous campaign on loan at Real Madrid - scoring seven goals in just 12 starts - but was unable to earn himself a permanent deal with the La Liga giants.
Emery has admitted that it will be hard to replace Bacca, who scored 20 La Liga goals last season. However, he says that the current transfer market offers a number of potential players to fill the role, including United's Hernandez.
He told Corriere dello Sport: "There is Chicharito, [Ciro] Immobile and other players that we are evaluating."
Following suggestions that the striker is not likely to be part of his plans going forward, Red Devils chief Louis van Gaal is looking to sell the former Guadalajara forward.
With just one year left on his current deal at Old Trafford, he could prove to be the bargain buy of the summer window.
Hernandez is also a target for West Ham United, as reported by the Daily Mail, and Orlando City, per the Orlando Sentinel, among others, but currently faces a four-week spell on the sidelines after he picked up a broken collarbone.
