Sorry Fedtard, I didn't realise you know more than Courier and Hewitt.
Before attacking other poster about this, you should realize that tennis "experts", commentators, retired players, even some active players have an agenda to promote tennis. They need to say stuff that give a positive light on current tennis (Djokovic, Nadal, Murray and younger generation). Fed is a declining legend on his way out. If they say stuff like "This Federer, even in his 30s and a step slower, still owning these youngsters with ease", it would not have a positive impact on casual and potential fans.
Murray in a recent interview (I forgot where I watched the video) was saying along the lines where he likes to find weaknesses in Fed's game when Fed was still at his best. And then, as though he doesn't want to came out sounding like he was dissing the current Federer, said something like "well, he's a still great player now". It can be implied that Murray think that Fed is not as good as he once was.
If you think I'm reaching with the Murray story, then there's a very easy way to know how Fed has declined. Use your eyes. Watch videos of Fed at his prime. Or just remember it, if you followed tennis long enough.
