Rafael Nadal sensationally knocked out by Australian teenager Nick Kyrgios in Wimbledon 2014 fourth round .

Australian great Rod Laver predicted his young compatriot would receive a grand slam yardstick from his fourth-round clash with Nadal.
Instead Kyrgios upended one of tennis' most stubborn operators, to rubber-stamp his breakthrough season.
Kyrgios will leave Wimbledon this summer having cut into the men's top 100 rankings for the first time, but he is by no means finished yet.
Nadal lost out in the first round in 2013 to Steve Darcis, a year after slumping to a second-round defeat at the hands of Lukas Rosol.
This year Nadal entered Wimbledon in prime fitness, reporting no issues with his long-troublesome knees, and boasting a ninth French Open title.
The 28-year-old from Majorca was unable to impose his usual grinding tactics though, with Kyrgios' powerful serve and high-octane approach prevailing.
Kyrgios admitted he gained motivation after hearing mother Norlaila give an interview back in Australia admitting Nadal was the pre-match favourite.
