A little bit late, but this is the conversation between David and Nadal:
RN: Ferreti, how are you?
DF: What's up Nadale, have you talked to him? ... (I guess those are two friendly nicknames, lol)
RN: Yes, he called me and I said yes immediately.
DF: He was the best, if it wasn't for him... have you talked to Feli?
RN: Yes, he's coming too, and Verdasco. Everybody is coming.
Bon Nadal to my favorite Spanish/Catalan boys, Ferru and Rafa! May they get a Davis Cup victory as an early Christmas present! (I'd love to get a visit from those guys, and Juanqui, too, for Christmas!)
