Southampton are eyeing West Ham goalkeeper Darron Randolph.
The Daily Echo says Randolph is one of several potential targets as Saints look to add depth to their goalkeeping department after the retirement of Kelvin Davis and the end of Maarten Stekelenburg's loan spell.
Saints feel they need to have an experienced player as cover for Forster, with Paulo Gazzaniga currently the only viable option if the England international was ruled out for any reason.
Claude Puel is targeting two more signings for Saints in this transfer window as things stand, with a back-up keeper and another attacking right back as cover for Cedric Soares the positions he feels need covering.
