The Mexican has been linked with a possible exit from Old Trafford as he struggles to secure regular first-team football.
His agent Eduardo Hernandez has now claimed that he has shunned offers from Germany, Spain and France to remain with United.
He told Mexico's ESPN Deportes: "I had meetings with a few clubs, I won't name them nor their offers, they are very interested in him. One of the top ten teams in the world are among those teams that were very interested in signing Javier.
"There was a club from Germany, one from France, and two from Spain and Italy each that want to have him. However, he is under contract with Man Utd and he somehow has to respect it in case there is an agreement between the parties."
The agent was asked if he sees Hernandez at United after the next six months, and he added: "I couldn't say that for sure, football is dynamic and his current situation could change tomorrow, so there are clubs that are interested, that like him a lot and trust him to succeed.
"He has achieved a high value in Europe's market and I can't say that there won't be anything concrete after the next six months. However, we do hope he gets minutes [on the pitch]."
