Galatasaray are interested in a loan move for Ramsdale, which would suit Southampton if they were to make an immediate return to the top flight.
A move to Turkey for the 27-year-old would be a blow to West Ham, but it would also open the door for the club to move for Sanchez.
A fresh start may be what is required for Ramsdale to make England’s World Cup squad next summer and with Galatasaray in next season’s Champions League he would be playing on the biggest stage against elite opposition.
