Five-time Olympic gold medallist Michael Johnson tipped hurdler Liu Xiang for a gold medal after putting the mainland's Athens-bound athletics team through their paces yesterday. Johnson wrapped up a three-day stint with 38 leading coaches and seven of the mainland's top sprinters, including injury-prone Li Xuemei, the Asian women's 100 metres record-holder. 'By offering our experience to help athletes and coaches through these clinics, I think Chinese athletes can improve,' said Johnson. China's best hope of a track and field medal in Athens rests with Liu, who unexpectedly won a bronze in the 100m hurdles at last year's World Championships in Paris before taking silver in the 60m hurdles at March's World Indoor Championships in Budapest. 'I think Liu's chances are very good for a medal, and it could possibly even be a gold. He has the fastest time in the world this year at 13.06,' said Johnson. Johnson accepted that the level of Chinese sprinting would not soar overnight after just one of his clinics. 'The sprinters are quick, which is good, and the potential is there, but we found a few technical mistakes in their training programmes. 'If we can correct those things, they could achieve much more,' said the former champion, adding that he hoped to return to offer training courses in the run-up to the 2008 Beijing Games. Johnson said that through specialist training, coaches could 'find out which athletes have the natural ability to reach top level'. The three-day session left the coaches wanting more. 'We did learn something from the clinic, but it did not fully satisfy our thirst for advice,' said one coach.
