Serbian tennis player Novak Djokovic spoke about the competition in men’s tennis. “There are a lot of strong players on Tour now. Federer and Nadal are still in the ranks. Murray and Wawrinka are returning. At the same time, a new generation has emerged, the main one in which is Zverev. New faces appear in our sport every day, and that’s great” – quotes Djokovic sport360.
