Fresh off a Paris Masters defeat, the new world number one says he's the only top-ranked player made to justify his place at the summit.
Alexander Zverev has reached the top of the men's rankings, but he is not happy about the conversation that came with it. After losing at the Paris Masters, the German let his frustration show over the scrutiny surrounding his new status.
Zverev argued that he has been singled out. In his view, no other player has been asked to explain and defend why it is fair for him to sit at world number one. That, he suggested, is a burden others who held the spot never had to carry.
The timing made his comments sharper. A defeat in Paris is never an ideal backdrop for a debate about whether a player deserves the top spot, and it handed critics fresh material just as he was trying to enjoy the milestone.
The rankings are built on results over a full season, and Zverev's position reflects that body of work. Whether the noise fades or grows louder will depend on what he does next as the season's biggest indoor events approach.
