Remember how everyone was counting Nadal out during the first week of 2010 Wimbledon? He needed 5 sets in both his R64 and R32 matches against Haase and Petzschner and everyone was talking about how bad he looked, how worn down he was physically, and how he had no chance of winning the tournament let alone ending the year at #1.
As it turned out, he met up with Robin Soderling in the QF, someone who had beaten him before in big matches and who had established a reputation of being a giant killer. He beat him, and carried that momentum to play his absolute best in the SF and F to win his second Wimbledon.
The same thing will happen here. He's going to be extremely motivated seeing Soderling, who he hates and absolutely does not want to lose to, on the other side of the net and find his best tennis. From there, he's going to have his 6th French Open, end Djokovic's streak, and dominate the rest of the year.
Have a nice day Rafa haters, you're about to be depressed again in 6 days.
