He manages to diss both Djokovic and Federer in the same answer
"Yes, it is clear that Djokovic is where he is because he deserves it, totally. But it is also true that, apart from being very good and being the best, he had a wee bit of luck that maybe could have facilitated us. For example, in Flushing Meadows, he played against Federer and he almost lost. And maybe, if we had played Federer in the end, we could have won ... Well, better not make these calculations. In short, you should always have a wee bit of luck."
