Sampdoria are working on a new contract for Belgium international Dennis Praet to raise the current €26m release clause.
The 24-year-old was snapped up from RSC Anderlecht in 2016 for €10m and his value has since gone up considerably.
He also received interest from the likes of Juventus, Inter, Napoli and Roma.
According to La Gazzetta dello Sport, Samp are eager to secure his status with a new contract to June 2023.
Above all, it would increase the release clause above the current more than affordable price of €26m.
