Philipp Kohlschreiber, Jannick Sinner & Martin Stepanek on coaching Borna Coric

An incredibly honest chat with Martin Stepanek, coach of Borna Coric, which touched on working with one of the game’s finest young players who perhaps lost his way a bit form and fitness wise last year. We also hear from two men at opposite ends of the age spectrum - 18-year-old Italian Next Gen Champion Jannick Sinner and German veteran, he of the wonderful rolling single-hander, Philipp Kohlschreiber.
