In the beginning, my idea was to be alive on Sunday because on Sunday anything can happen, especially knowing Fernando and Nicolas.

In the fifth point, anything can happen. Nicolas, he's special for that. I don't know about how Blake is going to react playing the fifth match. I hope we get to the fifth match.

I did hope that Andy didn't get a comeback in these two days. I think he's coming back. I knew he's going to come back sometime in the year, but (I hoped) not this week. Unfortunately for us, he came back on Friday and Sunday. He played his best tennis I think today, for a long time. I don't know what he said. But I think he played a very good match.

The only way to get confidence is to practice very hard. We've been doing that the last eight days in Palm Springs, working very, very hard, playing five hours of tennis and working in the gym.

Beat the U.S.? It would be the biggest win in the history of sports in Chile after the Olympics. Especially playing on grass, playing the U.S. They have three top-10 (players) in the world, the No. 1 doubles in the world. Can you imagine? It would be a big surprise. It would be a big event in Chile if we beat them.

When they play for their country, they put something more. And Davis Cup is different from playing in tournaments. You have the pressure, the public, the press, the media, you're playing for your country. It's very interesting. I played and I know what it feels like. You can play good or you can play bad.
