Which Nick Kyrgios will turn up at the Laver Cup in Chicago? This competition brings out something special in the talented Australian.
He's the man with whom you never know quite what you're going to get. The 23-year-old is one of the most polished players out there and delivers more tweeners than a hot dog vendor.

"I don't really care to be honest, I just do my thing," said Kyrgios. "I play the game how I want it to be played. I don't really idolise anyone and I don't follow anyone."
