PARIS, May 21 (AFP) - For 10 years now Michael Chang has been trying to turn back the clock to 1989. It was then that the gritty American baseliner enjoyed the finest moment of his tennis career - winning the French Open at the age of just 17 years and three months. He was the youngest male Grand Slam champion ever and looked to have a glittering career ahead of him. While he has enjoyed considerable success throughout the past decade, Chang has never since managed to win another Grand Slam title and is currently struggling to maintain a place in the top 50. His hopes of success at this year's French Open were dealt a devastating blow on Friday when he was drawn to face world number one and top seed Yevgeny Kafelnikov of Russia in the first round. Kafelnikov, the Australian Open champion and a former winner at Roland Garros, is always a formidable opponent at Grand Slam tournaments. Chang, though, remains one of the most dangerous floaters in the draw - a counterpunching stylist who is at his most dangerous on slow red clay courts like the ones in Paris. "I'm healthy again and I've won in Paris before," Chang said. "So why can't I win again?" Certainly no-one can afford to take lightly a player who has won 34 ATP Tour titles and has finished in the yearend rankings top 10 no fewer than seven times. Despite this being his 12th year on tour, Chang is still only 27. This year, though, his form leaves a lot to be desired and he has won only nine of his 20 matches on tour - the reason his ranking has slipped from a career high of number two to its current 50th. The little American often casts his mind back to 1989, where he came from two sets down against three-time French champion Ivan Lendl in the round of 16 to win a match that lasted nearly five hours, then beat Ronald Agenor and Andrei Chesnokov before defeating Swede Stefan Edberg in the final after trailing two sets to one. Since then he's been runner-up at the French Open in 1995 and runner-up at both the Australian and US Opens in 1996 without managing another Slam title. Last year, when he was plagued by injuries, he failed to make it past the third round of any of the Slams. Chang says he has no regrets that success came to him so early in his career. "I wouldn't change a thing," he said. "Whenever you have that type of opportunity, despite your age, you should take full advantage of it."
