Career
Schoonjans started his youth career with Stade Leuven, before it merged into Ohio Leuven in 2002. With Ohio Leuven, he promoted up two levels from the Belgian Third Division to the Belgian Pro League as the club got promoted in 2005 and 2011. In these ten years, he featured in 150 matches for Ohio Leuven, scoring 18 goals in the process.
During the first half of the 2011-2012 season however, he was surpassed by Bjorn Ruytinx and Derick Ogbu, only allowing him to make three substitute appearances, of which one was in the Belgian Cup.
He was loaned out for six months to Belgian Second Division team Sint-Niklaas during the winter 2011-2012 transfer window, but released upon return. He subsequently signed a full contract with Sint-Niklaas.
