Australian Open 2017: Five reasons why Rafael Nadal will defeat Roger Federer in the finals

#3 Nadal is back to prime fitness, while Federer might struggle

Federer returns to court after an injury time-out during the semi-final match

The way Nadal has recovered from his wrist issue has been remarkable in itself, especially when you look at how other players have had their careers damaged by such an injury. Critics and pundits around the world had written him off and had stated emphatically that he would never win a Grand Slam again, but the Spaniard has proved them all wrong.

Federer, on the other hand, might not be at his peak in terms of fitness. Only in the semi-final, the Swiss needed treatment for what is believed to be groin soreness. It is easy to forget that he is 35 and is contesting in his first Grand Slam since injuring his left knee at Wimbledon in July.

Yes, the Swiss will get an extra day to rest his sore limbs but Nadal has always been known for his superior fitness and stamina. Now, with all injury concerns behind him, the Spaniard will be pumped up and raring to go. And if the match goes past the fourth set, Federer might have something to worry about.
