Q: “What do you like about Rafa as a person?”

ROGER FEDERER: “Well, he’s always in a good mood, you know. I have never seen Rafa come along and - I’ve seen him tired, but not in a bad mood, you know. So that’s what’s nice about him. He’s friendly, he’s always the same guy. He doesn’t come in once and he doesn’t know who you are, the next day he remembers, you know. He’s always very straight and very polite and yeah, we enjoy each other’s company and it’s nice to see him do well and it’s also obviously nice to play against him.”
