ONE would think that Fiji's sevens sorcerer, Waisale Serevi has seen it all and done it all, here at the Hong Kong Sevens. For a man who has twice won the Best and Fairest Player of the Tournament, and for one who has been the inspiration behind Fiji's three successive Cup titles from 1990-92, is there anything else to achieve? ''Yes. There is one thing I have not done as yet and which I want more than anything else now,'' says Serevi. We wait with bated breath, trying to think what has eluded this extraordinary player with the gifted hands and magical feet. A player who in the past few years has averaged 80 points per tournament and eight to 10 tries; one who has single-handedly brought the might of Australia and New Zealand to their feet - and easily won the admiration of the crowd for his audacity. Is there anything more this player, who has dominated the tournament and become a household name, can want? ''I want to bring my wife to Hong Kong next year, with Fiji as the reigning Sevens champions,'' says Serevi. Impishly he adds: ''Of course that is if I'm picked for Fiji''. It is typical of the man that his only doubt, even if it is in jest, is whether he will be picked to play for his country. There is no question at all in Serevi's mind about Fiji winning the title tomorrow. Confidence bred on a winning habit, perhaps. Or maybe just a strong ego. Last year, at this time, Serevi was single, married only to his rugby. That all changed after the Fijians returned home in April, disappointed with not winning the inaugural World Sevens at Murrayfield, Scotland. On May 15, 1993, the will-o'-the-wisp Serevi was well and truly tackled by his childhood sweetheart, Karalaini. ''I have known her for a long time . . . since schooldays,'' says Serevi. ''She wanted to come to Hong Kong this time, but could not make it.'' That was because baby daughter Una decided to make her grand entry into the world. ''She was born at 8.30 pm on the 31st January,'' says the doting father. With a two-month-old daughter proving a handful, Karalaini decided to stay at home with her parents and plan ahead to next year when she could come to Hong Kong with a more manageable Una. But Serevi has not forgotten his loved ones back home. ''The next best thing I can do is to go back with the Cup and give it to my daughter. That would be the best present I can give both of them.'' It shows how badly the loss to Western Samoa in last year's Cup final has affected the Fiji psyche. Outwardly, though, Serevi shows a calm demeanour. ''We have forgotten the game. That is history. There is no point thinking about what might have happened. Doing that won't help us in our preparations to win this time.'' He even says that he has forgotten all the victorious moments Fiji have had here. ''Just because we won, say for instance in 1990, it won't help us win on Sunday.'' It is mind-boggling to think that this will be Serevi's sixth appearance at the Hong Kong Sevens. Just a wet-behind-the-ears teenager when he made his debut, the 24-year-old Serevi is now worldly in the ways of the tournament - in fact, today he is the most experienced sevens player in the squad. Earlier this year, however, there were fears that Hong Kong would have seen the last of him, with rumours that Australian rugby league side the Brisbane Crushers had lured him with mega-bucks. Serevi emphatically denies he was ever interested. ''No way will I leave rugby union and switch to rugby league. I still like to play for my country.'' He can, literally, afford to feel this way. Although no sums were mentioned, it seems that he is quite happy with his current stint as a rugby player in Japan. In his first season for Mitsubishi Motors Rugby Football Club in Kyoto, Serevi is enjoying his 15s rugby. ''My contract ends in December with Kyoto. I would like to continue to play in Japan.'' When he is not playing rugby for his Japanese club, Serevi spends his time teaching English and learning Japanese. ''I'm good at both,'' says Serevi modestly. His Japanese is so good that ''I can go to a restaurant and be sure that I don't leave hungry. My Japanese is enough to get me around''. His English students are employees at Mitsubishi Motors. If his linguistic skills are as good as his ball skills, Serevi will soon be proficient enough to sell a fridge to an Eskimo. And the Japanese at Mitsubishi Motors can most probably say in one go: sorcerer-Serevi's-sevens-skills-simply-superb.
