When young Aussie Nick Kyrgios beat Rafael Nadal at Wimbledon (2014), many tennis fans thought "Waw. Here is a supremely talented youngster who can stop the domination of Big Three & start winning grandslams". Its 2020 now & he has not won a single major. Some experts say that its his attitude problem that has never allowed him to reach the top. He has abused several players on court & also during press conferences. The bad has often overshadowed the good. His service game is powerful, his trick shots can be spectacular. He can dominate many top tier opponents at will. However, he has often failed to sustain his extraordinary skillset through an enitre tournament. His use of abusive language against Stan Wawrinka during a match is well known to all tennis fans. At the Italian Open in 2019, he threw his chair on court & walked off during the match against Daniil Medvedev. Suddenly we feel whats wrong with this guy. Only 3 players in history have beaten Roger Federer, Rafael Nadal & Novak Djokovic the first time they played against each of them. Dominic Hrbaty, Lleyton Hewitt & Nick Kyrgios. He has a 100% record against Novak Djokovic winning both times he faced him. Whether purists like it or not, Nick Kyrgios is a box office player. Fans are always on the edge of their seats at arenas he competes in & social media is abuzz when he plays. He needs to be consistent & control his temper if ever he has to win a grandslam in near future.
