Style of play
Kühn was described by the Bundesliga website as "a player who loves nothing more than to have the ball at his feet and dribble at his opponents, Kühn resembles a Coman type of player. With a high level of confidence, Kühn is not afraid to take risks by seeking one-on-ones and taking on his opponents, using his pace and excellent close control to deadly effect. Kühn is also a rather rare commodity in being left-footed, but he is equally at home on the left or the right, or even behind the strikers as a support man."[23]
