There's always something happening. And Wimbledon will be no different.

Everything he does gets extra attention. It's almost because it's Kyrgios who's doing it, not because of what he's done.

He's not the only one to break racquets, argue with umpires and hit balls out of the court.

But when he does it, it makes headlines.

Don't believe me? How about underarm serving?

The tennis world went into meltdown when Nick Kyrgios used an underarm serve against Rafael Nadal at the Mexico Open earlier this year. But when cleanskin Kei Nishikori served up the cheap tactic last week, no one blinked an eyelid.

The tennis world loves to hate Kyrgios. Even though he's polarising, you can't wait to watch him. It goes to show that everything he does is interesting.

But it also shows he's treated with double standards.

The underarm serve was just the tip of the iceberg after Kyrgios saved six break points and three match points to knock the Spaniard out of the Mexican Open.

The pair have been locked in a war of words since the heated clash, with Kyrgios dubbing Nadal "super salty" and the Spaniard accusing the Canberran of lacking respect.

Even Nadal's uncle Toni weighed in. He stood by his nephew's comments but added "[Kyrgios] lacks education and smartness." And of course, that didn't go down well with the Canberran.

That's why Kyrgios' potential second-round showdown with Nadal is the talk of Wimbledon.

Fresh off his 12th French Open triumph this month, Nadal needs no extra motivation to settle the feud on court.

The world No.2 was controversially relegated to third seed behind Roger Federer, despite being ahead on ATP rankings.

But Nadal isn't Kyrgios' biggest obstacle from making the third round. It's Jordan Thompson.

Kyrgios will play in-form Thompson in an all-Australian first-round clash at Wimbledon on Tuesday. The compatriots have never met on tour and Thompson will be anything but an easy-beat.

The Sydneysider has risen 27 places this year, sitting just one spot below Kyrgios at a career-high No.44 in the world.

Thompson has made an impressive start to the grass-court season, winning six of eight matches. The 25-year-old made the final in Hertogenbosch and the Antalya semi-finals in Turkey last week.

Meanwhile, Kyrgios has won only one match since pulling out of the French Open with illness.

But Kyrgios struggles more against the lesser lights than against players like Nadal. It all started when he upstaged the Spaniard at the All England Club as a 19-year-old on debut in 2014.

He holds a 2-0 record over world No.1 Novak Djokovic and defeated Federer in their first-ever meeting in 2015.

Yet he hasn't made a Grand Slam quarter-final in more than four years.

Moments of brilliance and electrifying wins over the world's best have been marred by major upsets to lower ranked players. The controversial Canberran has been criticised for laziness and throwing away his talent.

But the chance to repeat history and knock Nadal out of Wimbledon could just be the motivation Kyrgios needs to defeat Thompson.

Tennis legend John Newcombe agrees, believing the Canberran will 'bust his guts' for a chance to tackle Nadal in the second-round.

"He fancies himself against Rafa, especially on grass," Newcombe said. "He seems to play his best tennis when he's got nothing to lose. It could be an interesting match after all the talk."

Victory over Thompson would likely set Kyrgios up for a heated showdown with Nadal on Thursday, with the Spaniard kicking off his campaign against Japanese world No. 258 Yuichi Sugita.

Kyrgios has pulled out all stops to beat 18-time Grand Slam champion and squared their head-to-head record at the Mexican Open earlier this year.

The 24-year-old defeated three top-10 players - Nadal, Alexander Zverev and John Isner - to claim his fifth title at Acapulco.

Kyrgios defied nearly everything to make the Mexican Open final. A bout of food poisoning nearly forced the Canberran to retire in the quarter-final. A sneering, distracting spectator provoked him to fire back mid-game. Drug tests, injuries, cramps - you name it - motivated him to silence the critics and play some of his best tennis yet.

And why? He had nothing to lose.

Wallabies coach Michael Cheika will have to start putting his World Cup side together after the ACT Brumbies return from Argentina this week.

Brumbies players will join the Wallabies for fitness training in Sydney to prepare for the international season. Scott Sio, Rory Arnold, Folau Faingaa and Allan Alaalatoa are Wallabies certainties, while David Pocock races against the clock to be fit for the World Cup. Tom Banks, Christian Lealiifano, Tevita Kuridrani and Sam Carter are also in the running for selection.

The Wallabies have just five Tests to prepare for the tournament, starting with the South African Springboks on July 21.
