Kavlak is a defensive box to box midfielder. At club level, he is deployed in the holding role and is key in midfield with his tireless running and endless stamina. He is also a hardworking leader and although not being known for unsportsmanlike acts, he is known to be a hatchet man in midfield. Kavlak is often accompanied by another more offensive central midfielder such as Manuel Fernandes and Oğuzhan Özyakup. At international level, however, he has most prominently featured in a more advanced position in front of a holding midfielder.
