Sandro is said to have informed Everton of his desire to leave Goodison Park ahead of next week's transfer deadline, and has been linked with moves to various Spanish clubs - as well as Newcastle United.
However, it is a quintet of Premier League sides which lead the betting, after Bet Victor opened a market on the 22-year-old's next club.
Newcastle are the early favourites at 2/1, trailed by West Brom, Swansea and Brighton & Hove Albion at 8s and Huddersfield Town 10s.
Newcastle are said to have bid for Feyenoord striker Nicolai Jorgensen, while HITC Sport understands that Brighton are set to add Leicester City's Leonardo Ulloa to the recent capture of Jurgen Locadia from PSV Eindhoven.
And that could leave the door open for West Brom and Swansea to move for Sandro, who cost Everton £5.2 million last summer, off the back of a 16-goal season at Malaga.
Should West Bromwich Albion / Swansea City make moves for Everton's Sandro Ramirez?
