Wolverhampton Wanderers are short of defensive options after Mike Williamson's loan was terminated early.
McNair has not had much first-team football at Old Trafford so far this season, and Kenny Jackett is reportedly hoping to do a deal for the young defender.
Wolves do not have many options in defence at the moment, after Mike Williamson’s loan from Newcastle United was terminated early.
Williamson had made a good impression at Wolves, but Jackett’s side will have to cope without him for their match against Rotherham United at the weekend.
Wolves do have Ethan Ebanks-Landell available to replace Williamson, but the 22-year-old is still learning the game, and the pressure is on at Molineux.
Wolves have made a poor start to the season, and they desperately need to start collecting wins at a more regular rate.
As a result, Jackett is said to be keen to increase his options, and McNair is in his sights.
The young defender has shown signs of potential during his fleeting opportunities for United during his career so far, while he also played a role in helping Northern Ireland to qualify for Euro 2016.
If Wolves do make a bid for the youngster, they are likely to face competition for his signature, as Burnley and Blackburn Rovers are also said to be interested.
