Ever wonder why Federer has been so complimentary of Murray as of late? The more Murray achieves the less Nadal can.
After his massive 2010 it looked highly likely Nadal could catch up to Federer but since then he's only got one major closer in the last two years - two years right in the middle of his prime.
I'd say unless he wins two majors in 2013 his chances of overtaking Federer are all-but gone.
