Newcastle goalkeeper Karl Darlow and Watford custodian Daniel Bachmann are under consideration by Manchester United as a back-up signing to offset the expected departure of Dean Henderson.
Darlow, 31, has been suggested to United by Newcastle in a potential exchange with Henderson, who is hopeful of joining Eddie Howe's side.
Former Nottingham Forest goalie Darlow is aware of discussions but is currently on a post-season holiday. Darlow played twice against United last season, saving a Bruno Fernandes penalty in Newcastle's 4-1 home defeat.
