Although United maintain their support for Carrick, reports offer differing assessments of the potential candidates should that backing disappear.
The Sun reports that senior United figures regard Brighton boss Hurzeler as the outstanding candidate currently working in the Premier League.
The Telegraph, meanwhile, identifies Nagelsmann as an expected leading contender if Carrick is dismissed and reports that the former Germany manager would welcome the opportunity.
Neither report indicates that United have decided to replace Carrick.
