Serero has completed a three-year deal that is subject to a medical test.
Vitesse confirmed on their official Instagram page Serero would undergo a medical examination today.
The Bafana Bafana midfielder’s contract with Ajax Amsterdam is set expire at the end of June.
Serero missed out on a call-up to the recent Bafana Bafana squad that beat Nigeria in a 2019 African Nations Cup qualifier in Uyo due to the lack of game time at Ajax.
