The Dutchman is not someone Ralph Hasenhuttl will count on for the coming season, per HLN in Belgium.
He does not even have a Premier League squad number.
The 26-year-old last played for Southampton in 2018, and Brugge will attempt to sign him.
According to the source, Brugge cannot sign him for the £7.3 million Southampton want.
They would prefer a loan move.
