It had been suggested that the Mexico international could be set to swap Old Trafford for the San Siro in a move that would involve 19-year-old midfielder Mateo Kovacic going the other way.
Mexico manager Miguel Herrera had previously claimed that Hernandez was frustrated with a lack of first-team opportunities at Old Trafford, having started just four Premier League games this season.
However, his agent Eduardo Hernandez denied speculation surrounding the striker and insists he has had no contact from either club.
"I think these are just rumours. I have no news of Inter and Manchester United have not let me know anything about a possible offer," he told calciomercato.it.
"The same goes for the other teams that have been linked to my client, to date there is nothing concrete."
Speaking of a potential summer exit, he said: "Currently, we are not able to say it because we should talk with United, the club with whom Javier still has several years of the contract.
"At the moment we have not planned any meetings with the Red Devils."
