Not even a collection of Grand Slam titles and a monopoly on the sport more protracted than that of Pete Sampras or Roger Federer would allow Jo-Wilfried Tsonga to contemplate referring to himself as The Greatest. Such boldness is not for normal men, not even those who stand on the brink of a Grand Slam title that would come at the climax of an astounding fortnight-long performance heralded by former champions as the most exciting and unexpected breakthrough at a Grand Slam tournament since Sampras at the US Open of 1990.

However, the legend that is Muhammad Ali is more than just an inspiration to the young Frenchman, to whom he bears a decent resemblance. Should Tsonga beat hot favourite Novak Djokovic in this morning’s Australian Open final, which is being heralded as a changing of the guard in men’s tennis, he believes that he could transfer a dusting of the Ali magic from the boxing ring to the tennis court.

Tsonga’s father, Didier, once an Olympic handball player for the Democratic Republic of Congo, was a youthful spectator at that momentous fight in Kinshasa more than 33 years ago when Ali recaptured the world heavyweight crown from George Foreman.

He even passed on a photograph he took of the Rumble in the Jungle to his impressionable young son, who in the eyes of many has floated like a butterfly and stung like a bee through the first six rounds of the Australian Open.

Ali is the nickname that has been affixed to Tsonga throughout the tournament. He has celebrated each victory with a dance that is not as unique as the Ali Shuffle but is still intoxicating. He has even usurped Djokovic as the event’s favoured entertainer, his joyous jigs grabbing more attention than the Serb’s selection of impersonations of the serving styles of Maria Sharapova, Andy Roddick, Fernando Gonzalez, Rafael Nadal and Federer.

Tsonga revels in the limelight: “Maybe I have his [Ali’s] personality on the court. I am thinking about him more and more. I have watched DVDs of him. Maybe I think I have the same tennis as his boxing.”

But does the unseeded 22-year-old have what it takes to carry on where he left off with his annihilation of Nadal in the semi-finals and pound Djokovic into submission to become the first French men’s champion of Australia since the Bounding Basque, Jean Borotra, in 1928?

It is a long way, geographically and chronologically, from a week in south London seven months ago that Tsonga and his coach, Eric Winogradsky, consider as formative to his career as anything that has happened at Melbourne Park in these past two weeks.

Like any self-respecting Frenchman during the second week of Roland Garros, Tsonga yearned to be competing on the Parisian clay rather than the damp turf of Surbiton’s Berry-lands. To say that the Surbiton crowds can be counted on the fingers of two hands is an overstatement. “It was a sad situation for me because I wanted to be at the big tournament in my country, not the small one in England,” he says. “But now I am here doing what I have done, so maybe it was a good choice for me.”

He not only won the Surbiton Trophy and pocketed the winner’s cheque of £3,600, he also found time to drive across the Thames three days running to qualify for the Artois Championships at Queen’s Club, where he reached the third round. “In total, he played 12 matches in 10 or 11 days, which gave him a lot of confidence. That was the week when his career really changed course in the direction we are now heading,” says Winogradsky, who began coaching the muscular right-hander five years ago.

The experience, added to a notable straight-sets second-round win over four-times Queen’s champion Lleyton Hewitt, convinced Tsonga that he was again competitive after a herniated disc in his lower back had halted his progress following an exemplary junior career. “He always wanted to be the complete player,” says Winogradsky. “From the beginning he wanted to be able to play from anywhere on the court. He knew it would take a lot of time to do that, but he’s still very young, and what has happened here is such good news.”

Loyalty is clearly a quality that Tsonga values highly. Over the past couple of years the multi-millionaire French industrialist Arnaud Lagardere has funded a squad independent of the French Tennis Federation (FFT) and based next to Roland Garros in Paris’s Stade Jean-Bouin. He lured Patrice Hagelauer, the former performance director of Britain’s Lawn Tennis Association, and also boasts Richard Gasquet, Australian Open doubles finalists Michael Llodra and Arnaud Clement, Fabrice Santoro and Amelie Mauresmo among his collection of players. Tsonga was invited, but he took the view that the FFT supported him through his 18 months of enforced inactivity and he feels a debt that needs to be repaid.

Today he stands to pocket £650,000 by beating third-seeded Djokovic, who brilliantly ended Federer’s tournament in Friday’s semi-final and showed that he has matured immensely from the player who squandered a great opportunity to take what might have been a decisive early lead in last September’s US Open final.

Djokovic, too, has come a long way from the player who was rumoured to be seeking tennis “asylum” in Britain nearly two years ago. After the failure of Ana Ivanovic in the women’s final against Maria Sharapova, he still stands to become the first Serbian Grand Slam singles champion.

Unlike his more robustly built opponent this morning, Djokovic had not dropped a set in the tournament and rarely looked anything other than a potential champion. But, like everyone else, he has been entranced by the Tsonga performance. “It’s amazing for the sport,” says the 20-year-old. “The dominance of Federer and Nadal was amazing for the past couple of years, but to see something new is great for tennis lovers around the world.

“Every sport is waiting to have some new faces. Tsonga is coming up. He’s an amazing athlete who has played some impressive tennis these past two weeks. It’s going to be very interesting to see us two youngsters playing against each other.”

It is not the final most people expected, but it has created more excitement and speculation than the familiar prospect of another intense struggle between Federer and Nadal.

Of course the Swiss king and the Majorcan prince have not been dethroned permanently; they will return to fight many a great bout. For the time being, however, the tennis world savours the thought of this look to the future.
