The reported options offer contrasting solutions. Gunn, aged 30, is said to be available after leaving Nottingham Forest, although the update says he made only one appearance last season behind Matz Sels and Stefan Ortega.
His appeal may extend beyond recent match rhythm. The report highlights his previous connection with Jason Wilcox, United’s football director, from Gunn’s time in the Manchester City academy. That familiarity could help explain why he has emerged as a concrete option.
Darlow, meanwhile, would bring greater recent involvement. The 35-year-old reportedly started 22 matches for Leeds United last season and is approaching the end of his contract. His experience could make him a dependable short-term addition, particularly if United want competition without immediately committing to a major transfer.
The bigger question concerns the existing squad. Onana has reportedly been told that United are open to negotiating his departure, though no exit is confirmed. Bayindir has also been linked with a return to Turkey amid reported interest from Besiktas.
The report says Senne Lammens has taken the No. 1 role, creating a potential need for a goalkeeper who can handle pressure without destabilising the hierarchy. Gunn’s limited recent football and Darlow’s age underline the trade-off: one offers a longer runway, while the other brings immediate experience.
United’s recruitment team must decide whether it wants a challenger, a dependable deputy or a temporary safeguard during a period of transition. The next stage of pre-season should clarify Lammens’ status and whether Onana or Bayindir remain part of the group.
The goalkeeper picture will be one of the club’s key storylines before the Champions League schedule begins.
