Leon Klassen is a dynamic Russian left-back who has taken his talents to Austria with Grazer AK. Born on May 29, 2000, the 25-year-old, valued at €600,000, is a modern full-back known for his explosive pace and relentless runs down the flank. Weighing 69 kg and standing 173 cm tall, Klassen combines agility with endurance. His professional journey began in Russia, where his attacking prowess from the defensive position quickly made him a standout. A move to the Austrian second division with Grazer AK has allowed him to further develop his game, becoming a primary source of width and crosses for his team. Defensively, he is tenacious and uses his speed to recover effectively. Although still early in his career abroad, Klassen has already helped his team mount a serious promotion challenge. His style is perfectly suited to the modern game, where full-backs are expected to be key offensive weapons, and he is on a path to potentially feature for the Russian national team.
