WEIRD. Michael Chang has funny idea to train Nishikori

Kei Nishikori will play his last match of the round robin of the World Tour Finals against Marin Cilic. The Croat is almost 2 meters tall (1.98mt), and Michael Chang, Nishikori’s coach, had a fantastic and creative idea on how to train the Japanese to return high bouncing balls.
