Wow,these two haven`t played for over a year and i doubt they will play a lot of matches this year.Beeing nr.3,4 seeded in the big events it`s unlikely both Nadal and Djokovic will miss the finals so this match is a rarity.
It will be an interesting match for sure.Both guys are serving pretty well so it could come down to 1 or 2 chances.
Murray played better than Rodger today, but you just neve know. I always expect Federer to win their matches, I dont know why. Based on today, I'd say Murray to win in two sets. Probably two very tight sets.
