Andy Murray believes that youngster Alexander Zverev will eventually move up in the rankings, but said that the 18-year-old German has a lot of work ahead.
Murray crushed Zverev, 6-1, 6-2, 6-3, in the first round of the Australian Open.
The former No. 1-ranked Boys’ player, now ranked No. 83, is very tall and agile. But he was pretty frustrated against the two-time Grand Slam champion.
