Rafael Nadal was asked how he and Roger Federer have evolved since they faced each other in the 2008 Wimbledon final. The Spaniard said: "I don't think we improved much. I think we managed to add things because we lose things on the other hand, no? We need to add new things because of the age, we are losing another thing from the other side.
The only thing and probably the only reason why we're able to be where we are is because we love the game and we have big respect for this sport. My clear answer was I am running less so I need to serve better. I probably cannot play 20 weeks per year any more, so I need to reschedule my planning to improve things to be very competitive every single time that I am on court.
Of course, I am serving better. Of course, I am hitting the backhand better. Maybe volleying better, slicing better. But even like this, I don't know if my level today will beat my level of years ago. In terms of improvement, I don't know.
In terms of readapt my game, readapt our game, talking about me and Roger, for sure there is lot of things that we find a way to keep being one of the best of the world", concluded the 33-year-old who defeated Sam Querrey on Wednesday.
