I didn't see this interview, but I read about it after the match. Nole was asked whether the support for Federer at Wimbledon (even with the sound down it was obvious) bothered him. He replied that no, he had a little trick that he used. Silly though it might be, he pretended the crowd was shouting "Nole, Nole, Nole," and it sort of worked for him. That seemed so forlorn, I wanted to hug him. In the end Djokovic will very likely end up being Henry Aaron to Roger's Babe Ruth.
Then again, he may be the last man standing. Fed and Rafa are very likely to retire first, and then what are tennis crowds going to do? They will adore Nole because he sure paid his dues, and gracefully at that. He will be the only one of the Big Three still playing and a living memory for all tennis fans of a Golden Age that will never come again, at least not in any of our lifetimes. If he can wait long enough, crowds will eventually be shouting his name, too.
