"I respect it. I think he's doing great against me," 16-time Grand Slam champion Federer said after his 6-7 (5), 6-2, 7-6 (5), 6-4 defeat in the Australian Open semifinals. "It is what it is. At the end I care about my titles, if I'm happy or not as a person. Head-to-heads for me, I mean, are not the most important. If I beat Andre [Agassi] 10 times in a row or Lleyton [Hewitt] many times in a row, at the end of the day I don't care. I remember the matches on that given day, that I played well against them or not, and I don't remember the head-to-head that much. All I know is that we've played many times, and either comes my way or his way. Rallies have gone a little bit more his way obviously."
