TENNIS- Swiss star Roger Federer has cautioned temperamental Australian Nick Kyrgios to understand work ethics to realize his full potential.
Both Kyrgios and Federer are playing at Shanghai Open. But Kyrgios suffered a surprise loss on Monday after an argument with the chair umpire.
“I think it’s really up to him where he wants to go and what his potential really holds,” said the 20-time Grand Slam winner.
“We don’t really know and I don’t think he really knows exactly what his potential is.
“And only through understanding work ethic and scheduling and whatever it might be, creating the right team around himself, only then can you unlock the potential really.”
Kyrgios, this week, also lost his status as Australia’s number one to 33rd-ranked Alex de Minaur.
