Navas will reportedly leave Spanish side, as Zinedine Zidane has made Thibaut Courtois number one in the squad.
Pepe Reina is the main candidate to replace Navas, however, 36-year-old Stekelenburg is an alternative for Los Blancos.
Dutch international has joined Toffees in 2016. This season, he's become the third goalkeeper in the squad, as Jonas Lossl was signed from Huddersfield to become Jordan Pickford's main replacement from the bench.
