Olderer is almost impossible to bagel due to his serve.At least Fed has been bagled less than Nadal (I think). So, who's tougher?
Even when he started losing, Fed is never that down on himself as much as "humble" Nadal. People say that he has huge ego but I think it's just his mentality.
True to some extent but as a teenager he had his on-court tantrums and was a bit of inconsistent. Otherwise he might have won slams earlier. When Peter Lundgren took over in 2000 he managed to somehow calm Federer down and then in 2003 came the first Wimbledon title out of many for example. Who knows what direction Federer could have taken without good coaching. Lundgren did great work with Rios too getting him into top10, helped Safin to reboot and almost helped Wawrinka to become a stable top player. His coaching results are very solidabout 0 GS
with nadal's mental strenght, federer would have been truly insecure and his game would most likely never have developed to the degree it did. people forget the fact that nadal was at the beggining of his career uncle toni's little toy. he did exactly what toni said, at the times he said it and how he said it. because of his insecure and uncalm personality, he needed a soldier-like coach in order to give his tennis style and career a strong sense of direction because he was mentally unable to give it all by himself. the kid has will power but he needed someone exactly like his uncle in order to accomplish something in life.
by contrast, federer fortunately didnt have that kind of authoritative figure as a coach when he was a kid or a teenager so his style developed more freely and with a stronger influence about the past greats, much like he wanted to play in the first place.
