Nick Kyrgios must get physically stronger to compete at the highest level, says Greg Rusedski
Former British No.1 Greg Rusedski has warned Nick Kyrgios that he will struggle to compete for Grand Slam titles unless he makes himself physically stronger. The Australian limped out of the Cincinnati Open in a crushing 6-3 6-2 defeat at the hands on American Taylor Fritz. Ad Kyrgios has enjoyed a successful year in which he made the Wimbledon final, as well as winning the singles and doubles at the Citi Open in Washington.
