He did congratulate Rafa, the difference is that Roger is an honest person, not an obsequiousness as another players. Too praise is false, all this guys wants to win. Rafaīs speech of: "Roger is the best, Roger is better than me, I love Roger, I have a picture of Roger in my doorīs room, Iīm just lerning, I have to improve a lot, Karanusic is favouriter than me, I though I was going to loose, I was so tired, I couldnīt even crawl" is annoying. I donīt find this humble. Sorry, I donīt want to be mean with Nadal, is a good guy, but I found Roger more sincere.
That's just wrong, Nadal is a great guy. I'm a fed fan. You have to consider Uncle Tony - He has always praised Federer and effectively told Rafa to model himself on him off the court. That's not a bad thing. IMO of all Tennis role models, of all sports, Federer is probably only second to Woods in terms of "role model".
Federer also happened to be a brilliant Tennis player too.
Federer is justified to cry. He works hard, expectations are so high (still). And he keeps losing in the Final in 5-sets to the same guy.
