Alexander Zverev is due to start rehab on his injured ankle next week, according to brother Mischa. Zverev was playing arguably the best tennis of his life against Rafael Nadal in the French Open semi-finals on June 3, before being cruelly cut down by a fall which tore his ankle ligaments and caused his retirement from the match. Ad/> Despite that setback, Mischa revealed that his brother has been putting in a daily routine of «sleep, breakfast, training, lunch, training» as he tries to bounce back from that disappointment, with Zverev set to finally begin rehab on his ankle shortly, having had to keep it in a cast since the injury.
