An informative talk with Nole’s coach. I definitely believe that winning the Davis Cup for Serbia changed something inside of Novak. It really seems to have helped mentally and emotionally transform him. His confidence is sky high, as it should be. 24-0 to start the year so far. 5-0 against Rafael Nadal and Roger Federer. The Australian Open, Dubai, Indian Wells and Miami titles. That’s as good as it gets for a start.
