There are a few question marks about Djokovic coming into this match--particularly questions of his mental state given his father's current health. However, when an athlete is in the moment, I believe that most champions play even better when having something like that on their mind. Djokovic barely survived against Tsonga and this match is only going to be harder for him.
However, I think Djokovic will play a fantastic match and these courts definitely favor him. They are not very quick at all and Djokovic is the better defender and can switch defense to offense almost instantly and that's exactly what you need when you play on these types of indoor hards. Murray is also one of the best in this area but Djokovic is just a little better in these areas.
I think it'll be difficult for Murray to win points on his second serve in this match so that's the main reason why I like Djokovic.
