The 21-year-old Croatian international is ranked among the best centre backs in the world due to impressive statistics. And Leipzig wants to take advantage of this to earn money from a potential sale of the player in the summer.

According to the report from Fichajes, RB Leipzig will not be willing to accept any bid from clubs below 100 million euros as Real Madrid, Manchester City, United and Chelsea are closely monitoring the situation around the player.
