VfB Stuttgart striker Serhou Guirassy's buyout clause has two different prices.
Guirassy is interesting the likes of Newcastle, West Ham and Borussia Dortmund, with the Germans at an advantage, says BILD.
While foreign teams can buy Guirassy for 20m this summer, BVB and fellow Bundesliga clubs need only put down 18m to sign the centre-forward.
In Swabia, those in charge are still hoping that Guirassy, who has a contract until 2026, will stay, given the club's qualification for the Champions League.
Guirassy has scored 28 goals in 29 games this season.
