Pretty unlikely that even 1 of them makes it all the way. It'll be interesting to see how their game reacts to Novak's exit. They certainly know how to beat Murray, and I think Murray can be vulnerable if they were to rise to the occasion, but Murray isn't the only man in their path. Confidence is definitely a factor for both of them. Nadal had an easy win today, if he puts a couple of matches like that together, maybe he gets some belief that he can do something. While Feds has never been shy of confidence, It doesn't look like he has enough right now to really make a dent here.
