Juventus have reportedly informed Stoke City that Mario Lemina will not be allowed to leave the Italian champions this summer for anything less than £20m.
It is understood that Stoke are desperate to sign the 22-year-old, who only signed a four-year contract with Juventus in April after spending last season on loan from Marseille.
According to Sky Sport Italia, the Serie A giants are keen to keep the Gabon international, but would consider an offer in the region of £20m, which would represent a £12m profit on the deal that they completed in April.
Stoke's Premier League rivals West Bromwich Albion have also been credited with an interest in the central midfielder.
