MELBOURNE - With a trophy cabinet straining at the hinges and a 53rd consecutive grand slam appearance looming, Roger Federer might be excused for feeling a little jaded ahead of his bid for a fifth Australian Open crown.Not a bit of it, the 31-year-old Swiss maestro said on Saturday, having passed his motivation test during punishing practice sessions in the off-season.Federer eschewed all warm-up tournaments for the year’s first grand slam, dropping off the radar altogether in favour of a hermit-like training regime and time with his family.The break, coming off a disappointing U.S. Open and loss of his ATP Tour Finals crown to Novak Djokovic, was seized upon as evidence his competitive fires were beginning to flicker out.Federer admitted to some trepidation before returning to the practice courts."I think it’s always a bit of a test for me going into the practice season,” the 17-times grand slam champion told reporters at Melbourne Park."Am I hungry and motivated to wake up, go on the practice courts for hours?” he told reporters at Melbourne Park, before affirming it was all systems go."There was not one problem. For me, that was good news. I was eager to improve my game, change it up a bit from all the tournaments I played this last few years.Federer has had to compartmentalise his job and family duties since becoming a father to twin girls in 2009."Today things for me make sense,” said the Wimbledon champion. "I know why I’m doing them. I know they’re necessary. Sometimes it’s not the thing you want to do every day of the year."But I know it’s only a handful of weeks, then obviously you give everything you have.”Like his masterful technique, Federer has exhibited a similar gift for managing his fitness levels and now trails only South Africa’s Wayne Ferreira (56) and Swede Stefan Edberg (54) for the most consecutive grand slam appearances.Nadal outRafa Nadal’s absence has taken care of one major impediment to Federer’s hopes of extending his record to an 18th grand slam singles title.However, he faces a tough draw and may need to overcome third seed Andy Murray in the semi-finals, continuing a rivalry that had Britain buzzing last summer.Federer beat Murray in the Wimbledon final, but the Briton exacted revenge in the gold medal decider at the London Olympics and brings a new self-belief to Melbourne after ending his long wait for a maiden grand slam title in New York.Federer faces unseeded Frenchman Benoit Paire in the first round but the prospect of an unenviable fourth-round clash with big-serving Canadian Milos Raonic lurks.His lack of competition in the lead-up to Melbourne was calculated but Federer conceded it might put him under extra pressure."I purposely didn’t play a lead-up tournament so that I’d be fresh for the beginning, hopefully going deep into the tournament,” he said.Agencies
