A product of the Saint Jan club in his native Antwerp, Driesen was lured to Spain in 2005 by Estudiantes, signing a five-year deal with the Madrid club. The center initially spent two seasons in their development programme, making a total of 14 ACB appearances, before being loaned to LEB teams Illescas and Palma in successive years. He returned to Estudiantes for the 2009-10 campaign, featuring 26 times, before moving to the Ethias League and Antwerp in 2012. His senior debut for Belgium came in 2007 against Israel and since then, he has made over 75 appearances for the Lions. On Twitter @yannickdriesen.
