Roger Federer, on the fast pace of the Paris Indoors courts this year: "It's nice that some tournaments have made the courts faster again. I'm not saying it should be the trend for all the tournaments, but indoors is supposed to be faster. We only have one indoor Masters 1000, so I think it should be the fastest one, which is the case.
