Alexander Zverev, who won Washington last week, is happy to hear Roger Federer and Rafael Nadal saying he can become No. 1 someday, but he knows he still has to really improve his game to be up there.
“It’s always nice to hear stuff from Roger and from Rafa, that they think I can become the world No. 1,” said Zverev, who is playing in Montreal. “They know what it takes. A lot of journalists say, ‘He might be a world No. 1, he might be a Grand Slam champion.’ But coming from fellow tennis players, it's something that I see as more value because they know how to do it. They always mention that me and Dominic [Thiem] might be the next two guys.
"But we both know that we still have a lot of hard work ahead of us. There's other young guys that are coming through, as well. We'll see what the future holds for all of us.”
