An unlikely friendship is developing in tennis between rivals Roger Federer and Nick Kyrgios. Federer beat Kyrgios at the Stuttgart Open semifinal in Germany earlier this month. Since his win, the two players have been gushing over each other in the press. Business Insider says Federer acknowledged that Kyrgios is a tough competitor. He even complimented Kyrgios by saying that their styles of playing are similar. Federer told reporters, "He plays very relaxedly, just like me when I was young."
