I think that Andy and Novak play better on a faster court and Indian Wells is quite slow, which suits Del Po, so that may be a factor to take into consideration.
Not really. I mean, Novak excels at the Aussie Open and that is one of the slowest, high-bouncing courts (it was slightly faster this year) on tour. Andy also has much more success against Novak on faster surfaces. The H2H on faster courts is 5-2 in Andy's favour or sth. similar. They don't play the same game, despite what a lot of people say. Although I'm not really sure what Andy's game is at the moment.
