Since Lleyton Hewitt won in 2002 only two names have appeared on the roll call of men\'s champions here at the All England Club. Roger Federer, six times a winner, and Rafael Nadal, who has taken the title on his last two visits, are clearly in the mood to extend that record. With both men coming through their first three rounds without dropping a set, what price a fourth Roger versus Rafa Centre Court final next Sunday? Yesterday\'s third-round matcheshad the potential to provide the two greatest players of the modern era with significant challenges, but they never materialised. Federer beat David Nalbandian, an opponent who has given him plenty oftrouble in the past, 6-4 6-2 6-4, while Nadal, having laboured through the first set against the big-serving Gilles Müller on Friday night, completed a 7-6 7-6 6-0 victory over the 28-year-old world No 92 from Luxembourg. Nalbandian, a contemporary of Federer\'s, was for many years one of the only players on the circuit who had won more matches against the Swiss than he had lost. The 29-year-old Argentine won their first five meetings as professionals and their head-to-head record stood at eight wins apiece as recently as three years ago. From independent.co.uk
