Carrick's side have endured a miserable start to the season, with just two wins from 12 games across all competitions, and the club could be forced into a decision imminently.
The former Bayern Munich and Germany manager is believed to be keen on the job at Old Trafford, having been a long-term target since before Carrick's summer appointment.
Should the board be forced to make a change in the near future, there is a growing feeling that Nagelsmann could be in line to take over, with other options also being considered.
Will Man United appoint Julian Nagelsmann?
Football Insider reported back in April that Nagelsmann was going head to head with Carrick for the Man United job, but the latter ultimately was chosen after his interim spell.
Contact has been made with Nagelsmann and other potential candidates to assess whether they would be willing to take the job, but it has not gone further than that as things stand.
"Yes, Julian Nagelsmann is somebody who has a lot of admirers on the Man United board," Brown told Football Insider.
"He's got that top-level experience at Bayern Munich and with Germany, so that certainly ticks one box, and he has been an option United have liked for quite a while.
"He's out of work at the moment, so I have no doubt they will have been in contact with him to assess whether he would be interested and make those initial moves.
Which other options are on Man United's radar?
Despite having emerged among the leading contenders for the Man United job, there are more options than just Nagelsmann on the Old Trafford hierarchy's radar.
The likes of Antonio Conte and Fabian Hurzeler have been spoken about in connection with the role, while names continue to be discussed as they weigh up their next move.
The former Newcastle United manager is taking a break from football after leaving St James' Park in the summer, but there is a feeling he could be lured back in by the right offer.
Reports elsewhere have suggested the former Newcastle boss is the favourite of sporting director Jason Wilcox, who himself has faced pressure in recent weeks.
