Federer and Djokovic are both multiple Grand Slam champions but that did not stop John doing the business against them last year! Del Po would have given John a good test no doubt he's a class player but it would be tough for anyone to withstand the barrage of 140 mph serves on these courts which are playing with more pace than previous years!
