Tony Pulis says West Brom will not sell striker Saido Berahino "unless it is right for the club".
Stoke made a bid in the summer for the 23-year-old, whose deal expires at the end of the season, while the Baggies made a third contract offer last month.
Potters manager Mark Hughes has said he remains "hopeful" of signing Berahino in the January transfer window.
But Albion boss Pulis told BBC Sport: "This club has looked after Berahino since eight or nine years of age."
Berahino has not played for the first team since 10 September and was sent to a conditioning camp in France to help him lose weight and regain fitness.
