Football Insider revealed on 1 July that Sunderland are planning to sign a new goalkeeper amid links to the likes of Marcin Bulka and Djordje Petrovic.
After missing out on a move for Bulka, who instead joined Saudi outfit SC Neom, the Black Cats have set their sights on Chelsea shot-stopper Petrovic.
As a result, Brown told Football Insider on 3 July that Southampton are interested in signing Patterson amid speculation about Aaron Ramsdale’s future.
The 25-year-old could be temped to leave the Stadium of Light in favour of playing regular first-team football should an acceptable offer arrive.
