Schut is a coach's signing after being recommended by fellow countryman Johan Neeskens and will join management's Ghanaian signings Emmanuel Baffor and and Mumasi Abubakar as the three new foreign signings.
Sundowns already have the allocated five foreigners on their books from last season in Elias Pelembe, Simba Sithole, Method Mwanjali, Solomon Okpako and Nyasha Mushekwi.
To open up the three foreign spaces to accommodate the new signings Sundowns have already pushed aside Sithole and Okpako while Pelembe is in the process of acquiring permanent residency having now spent five years in the country.
Sithole failed to break into the team last season while Okpako only played a handful of games before falling out of favour.
The other option that Sundowns have is to sell Mushekwi to any of the two Belgian clubs that have tabled an offer for his services.
Sundowns already have another foreign player Lionel Mutizwa parked at the club who is still battling to find a way out of the club.
Last season Sundowns was also forced to reshuffle their foreign listings with Nigerian striker Gbolahan Salami sent away before he even played while Eduardo Ferreira and Mutizwa were parked at Chloorkop.
The Brazilians already have two other foreign born players Dennis Onyango, Anthony Laffor and Esrom Nyandoro already playing as non-foreigners after acquiring South African permanent residence.
