At the Australian this year I noticed Almagro standing on the baseline to return serve and consistently hitting winners off the backhand return by using the opponent's pace. Makes him a lot more dangerous on hard courts than when he would stand 4 or 5 meters behind the baseline to return. Very impressed by him. I've noticed that Djokovic has stopped using the slice forehand when stretching to the right. Instead he's moving quickly to the right and hitting an aggressive crosscourt topspin. The old forehand slice he used to hit would float into the middle of the court and could be easily dealt with, while the aggressive crosscourt makes him almost unattackable. Hit it hard to him, he'll hit it back harder. Also I've noticed that he's become proactive after hitting a dropshot and quickly sneaking into net. He used to hit his backhand dropshot then just wait at the baseline and react to his opponent.
