Troicki never defeated Murray before, however they never played on clay either. Troicki prepared well for this tournament and he shows some good quality. He makes less mistakes and we can see that he's motivated to win as many games as possible.
All in all, I see no difference between them, however Murray really has some health problems after he'd fallen in the match against Berrer. Probably this game will not even start but if it will... I will back Troicki.
