Is Alexander Zverev really the best player in the world? Vote now

Alexander Zverev has enjoyed the best year of his career so far, having finally clinched not one, but two Grand Slam titles. He had never prevailed on the biggest stage before winning the French Open , beating Flavio Cobolli in the final to get his hands on the prestigious trophy. He followed up by claiming the US Open title last month, edging past an inspired Ben Shelton in New York. Those successes have propelled the German up the pecking order and he is guaranteed to finish the year at the top of the ATP rankings.
