I've noticed that Rafa and Uncle Toni have praised Federer at every opportunity since about 2006, and called him the greatest ever (long before he reached Sampras' slam record). Has this played a part in Federer's problems with Rafa? I know Rafa is extremely gifted, but for Federer to lose 5 straight slam matches to Rafa including TWO on hardcourt and one on grass, just seems like there could be more than one factor at play. I don't recall Djokovic or the Djokovic family praising Federer a whole lot. And I haven't noticed Murray doing it, as Murray has called Rafa 'probably the greatest player ever' rather than Federer. Maybe if Djokovic and Murray praised Federer more over the years they too would have had success at the slam level earlier. Maybe Federer isn't good at handling immense praise from his opponent. It wouldn't make a difference if Federer's opponent was weak (like Benneteau), but the praise would still get into Federer's head and make Federer struggle a bit (he needed 5 sets to beat Benneteau). Maybe Federer's ego is so overflowing with self-love that it can't take the praise when a fellow player strokes his ego further, and overflows and explodes into unforced errors.
