Rafael Nadal's victory at the French Open and Wimbledon this season means the two Grand Slam have been won back-to-back for three years in a row. Federer did the same last year and Nadal the year before.

Until Nadal's 2008 victories in both Paris and Wimbledon, no player had managed to complete the double since Bjorn Borg in 1980.

"It didn't happen since Borg," said Nadal, "Now last three years it happen.

So how crazy is the life?"
