Though Erik ten Hag may be keen to improve his options in the goalkeeping department, warnings from the past suggest he might be better trusting the Red Devil he knows.
First-choice keeper David de Gea is out of contract at the end of the season, with talks over a new deal continuing. De Gea is one of United's highest earners, with the Red Devils keen to bring his wage down as part of any extension to his stay at Old Trafford.
The Spaniard has mostly impressed this season, though has had some moments in which he has drawn criticism from Ten Hag. The decision over the future of the goalkeeping department is reminiscent of the one United faced when Peter Schmeichel left the club.
