Rafael Nadal

Melbourne: Rafael Nadal says the emergence of a new generation is just what tennis needs, while welcoming back Roger Federer to help him keep them at bay. The 14-time Grand Slam champ, is on the comeback trail after a wrist problem, which has seen him slip to ninth rank. Federer is also easing his way back after six months out with a knee injury. They will have their work cut out at the opening Grand Slam next week with not just Andy Murray and Novak Djokovic to contend with but an emerging new breed. "These guys are doing well," Nadal said yesterday.
