Djokovic never beat Nadal at the French Open before, and he did it in straight sets!
He hasn't lost a set yet in the tournament, and I think he's just going to keep on being a monster and destroy Murray.
Murray has played some great tennis so far, but his game against Ferrer showed his weaknesses. Luckily for him, Ferrer had a weaker service game.
Djokovic plays his last game as hard as his first, and if he brings the same power against Murray, there'll be no way to take a set from him. If djokovic losses one set, he'll probably short circuit and lose the match.
