Tennis legend Bjorn Borg tells me that what's missing in today's sport is more rivalry. 'In my time there was me and McEnroe and Connors where we built up excitement for people and the tournaments - today there doesn't seem to be any of that,' he says. 'Three or four years ago we had Agassi against Sampras which got everyone talking but we need new rivals today.' Borg, 42, who is in town for the NatWest Classic AFT Senior Tennis Championship at Hong Kong Country Club, says the game has changed because of technological advances resulting in better rackets and faster balls. 'It's not the players' fault because there is a lot of depth out there and some excellent players but I tend to see only one style.' Living in Monte Carlo and Stockholm, Borg spends most of his time playing on the senior tour, working on his clothing and fragrance lines and volunteering his time to give advice to young players at the Swedish Tennis Federation. He warns aspiring players that the road to the top is a long and arduous one. 'Young kids should learn how to lose and take their losses in their stride,' he says. There is one young player in particular which Borg has his eye on - his 13-year-old son. 'I spend a lot of time with my son and he tells me he would like to be a tennis champion. As long as he has the interest and has fun, we'll see what happens.' Borg doesn't coach him but gives him all his support and challenges him to a good few games. And he is careful not to push his son too hard. 'Parents should never force their children to do something they don't want to.' And does he miss being No 1? 'I retired at 27 and I have no regrets. Maybe then I could have had another five years and won a few more Grand Slams but it wasn't the most important thing in my life.'
