Spain wins Davis Cup with Nadal's win over Del Potro!

The score ended with 1-6, 6-4, 6-1, 7-6 (7/0). I can't wait to see this match, but has anyone seen it? 

I also read that Nadal doesn't want to do Davis Cup but focus on being number 1 again. Do you think those two things are mutually exclusive? McEnroe never thought that way.
