HITC Sport understands that Fulham youngster is set to leave this summer
The 19-year-old from Texas joined Fulham's academy in 2011 and made his first-team debut in 2014.
Now a regular in the first-team squad, Hyndman's performances have caught the eye of a host of clubs - but Fulham, like with Moussa Dembele, have failed to tie him down to a long-term deal and he is set to quit the club in the summer.
A Fulham source told HITC Sport: "He looks to be on his way, we have been told of a number of clubs who want him and are offering big deals, but United look to be in the strongest position."
With Dembele also set to leave this summer when his contract expires, Fulham will be losing to of their brightest prospects for next to nothing.
United are understood to be keen on landing Hyndman with a view to loaning him out next season.
