Mortensen's record as a professional player is not very good, and his career singles ranking is 30 1. However, as the coach of the Danish Confederations Cup, mortensen once coached Wozniacki, who is currently ranked first in the world. During the running-in period, Sister Na was most satisfied with Mortensen's confidence. As for his own depression, the experienced coach also gave Sister Na a lot of practical advice. In the previous competition, when Na Jie and Sanchez led at 5: 4 in the first set, Li Na applied for the guidance of the coach, and then Na Jie successfully won the first set. The process of gnawing the clay master made people feel the change of Najie and the skill of the new coach.
