as tennis fan, we must be objective.

I am a big Federer fan. Federer is not great in every area. His backhand return of serve is his weak point. He use it as transition ball before. It is great to see that Federer backhand return of serve is more aggresive than before this time(see how many points by his return of serve). Give him time to let his backhand return of serve more consistent. He will top Nadal in the near future, maybe Wimbledon or US open. I don't like Novak loss and retire way. But Novak return of serve is best. Nadal is super pusher. His coverage is best. But his serve is his weak point. I bet Novak win because Novak strong point return of serve will kill Nadal weak point serve. 而Federer却没有进步，只是原地踏步。There is no stat.to support this no sense statement.
