I wonder how someone can be a threat for #1 if he does everything worse than the current #1, lol. Serve - people always talk about Federer's serve, but I would rather have Nadal's. Federer has the speed but Nadal's serve has the accuracy and spin to find the other guy's backhand every time. Look at break point conversions in all of their matches and what percentage of their games they hold serve, and it is incredibly obvious that Nadal serves better. Forehand - Nadal has so much better placement and controls his forehand so much better on the run Backhand - Not even up for debate Volleys - people say that Federer is better volleys, but what about the last game of Wimbledon? You see Nadal hit amazing passing shots against Federer all the time, but rarely the other way around. Movement - Nadal is faster and gets into position much more easily, that is why he is able to put so much on every shot Mental - Once again, not even up for debate Hard courts - see most recent GS final and most recent Master Series 1000 tournament Grass courts - see most recent Wimbledon final, plus Nadal faced a much tougher field in his grass warm-up the week before Wimbledon Clay courts - this one is just total domination, Nadal goes down 1-5 or 4-0 on purpose just to practise his mental toughness. It worked so well, not only did he win the matches where he was down 1-5, the mental toughness practice let him win Wimbledon and the Australian Open too Other surfaces - neither player has done anything important on other surfaces in the past year Any takers? Federer might've had a better forehand and serve and volleys in his prime, but that time is long gone.
