And I assume that he's at home at the moment, before next week, the team will get together to prepare for the tie in Buenos Aires.
However, before leaving Miami, David took a moment to talk to Miguel Angel Bertulotto for Clarin.
About his chances of winning that elusive Slam, Delpo's comeback on the Davis Cup team, playing the Olympics and a few other things.
Here's the interview...
Q: At Miami, you lost to Janko Tipsarevic, a Top10 player you beat the week before at Indian Wells. Still, in the light of your excellent run in California and your move up the rankings, where you've gone from 74 up to 50, and with your tennis back in full force - can you still hope to win a Grand Slam?
David: No, I cannot in any way hope to win a Grand Slam. Djokovic, Nadal, Federer and Murray, the four at the top, have a very high level and there's a clear difference between them and the rest. Beating them at a tournament of this kind, and in what would basically have to be consecutive matches, that's impossible. At 30 years of age and having had three surgeries, I can't aspire to that sort of thing. I've come to terms with that.
Q: Do you think that for your career, not having won a Grand Slam is an unresolved matter?
David: I don't know if I think of it that way. When I came very close to winning one I didn't make it. Because my opponents were better, because they made the most of their chances, or whatever it was. I'm a contemporary of Federer, of Nadal... Now there are Djokovic, Murray... Basically no chance. With them around it wasn't easy to win a Slam. What can I do... Actually, I don't feel it's like an outstanding debt. It simply didn't happen.
Q: How do you like Del Potro's return to the Davis Cup team?
David: Very well. It's great that he's coming back because you always need to be able to rely on the best players. Hopefully, we can all do our part for the good of the team.
Q: There's a phrase that's been established about the chance of finally winning the Davis Cup: now or never. Playing at home fuels those kinds of expectations. Do you also think that it's now or never?
David: The journalists came up with that phrase. And I don't know if people think the same. We [the team] never said that. Playing in Buenos Aires, all you need is a good opportunity but we didn't say anything like that. It's true that the home advantage means we're the clear favourite against Croatia and we have to make the most of that situation. But the matches have to be played and won. We have to stay very calm and not put ourselves under any additional pressure.
Q: Would winning the Davis Cup be the perfect end for your career?
David: I don't know. What I want is to win it. Then we'll see what I'm going to do...
Q: Did you expect a performance like the one at Indian Wells? You reached the quarterfinal and there lost to Rafael Nadal but before that you beat Marin Cilic, Janko Tipsarevic and Jo-Wilfried Tsonga.
David: I played rather well, that's true. But I have to keep improving in the two aspects, tennis and fitness, in order to be more consistent against players like those who are at the top of the rankings. I know that this is the way, the right track, and hopefully, I can continue on it.
Q: Do you hope to be playing the Olympics?
David: Yeah, of course. But right now I'm not qualified. I hope that I can qualify and play there. That would be great.
