Zverev is out of control, no one can rival him right now. Nadal and Federer are old and broken down, and this young gun can challenge them even at their pocket slams. Zverev has three masters to his name, demonstrating his ability to dominate the field, and soon he will strike at the slams, winning three this year and then maybe all four next year. I'm predicting the only sets he drops are to Nadal at the French, otherwise he will win easily and handily.
