Expect fireworks in Kyrgios v Nadal Part III

London - The first time Nick Kyrgios faced Rafa Nadal at Wimbledon eight years ago the unseeded teenager blew the then world number one off court in the fourth round with a spellbinding display of fearless grasscourt tennis.

Five years later Nadal evened the score in a stormy second-round match in which Kyrgios, with his bad boy reputation firmly established, moaned about the Spaniard's slow play and launched a ferocious forehand straight into his body.

Australian Kyrgios recalled again this week how his manager had to drag him out of a club at 4am on the eve of that clash.

There is little chance a search party will be needed this time ahead of the pair's third clash at the All England Club in what will be the biggest match of Kyrgios's career.

The 27-year-old's path to his first Grand Slam semi-final has been a rocky one. A first-round five-setter against British wildcard Paul Jubb resulted in a fine for spitting, while his third-round blockbuster against fourth seed Stefanos Tsitsipas was one of the most toxic ever seen at Wimbledon.

Kyrgios revealed his good, bad and ugly side in that bad-tempered clash, after which his opponent and former doubles partner described him as having an evil side to his nature.

Since then, however, Kyrgios, once accused of disrespecting the sport by Nadal, has let his tennis do the talking and a switch appears to have been flicked.

Fully-focussed and keeping his trick shots in the bag, Kyrgios survived a five-setter against Brandon Nakashima, then overpowered Chile's Cristian Garin who described the Kyrgios serve as the best he had ever faced.

Kyrgios said his semi-final against 22-time Grand Slam champion Nadal would "probably be the most-watched match of all time" and while that might be over-egging it slightly, Wimbledon is buzzing with anticipation.

It is a clash of styles and personality like no other.

Nadal, who practised yesterday despite fears that an abdominal injury might rule him out, is known for his meticulous rituals between points. Kyrgios barely blinks.

Ultimate warrior Nadal, would rather pull out his own teeth with pliers than give up a single point. Kyrgios freely admits 'tanking' games just to throw his opponent off.

Nadal, twice a Wimbledon champion, reveres the sport's traditions and throughout his mind-boggling career has been the ultimate ambassador for tennis. Kyrgios once said he doesn't even like tennis and enjoys nothing more than taking swipes at the establishment, on and off the court.
