There is a lot of pressure on tennis players like other sports that are singular like you're not on a team. When all the pressure rides on your shoulders, it can be a lot different. Team sports you share those moments with the teammates. You share the pressures. You share the wins. You share the losses. You have a coach that can change the course of matches. But in tennis you're out there by yourself. There are no caddies. There are no coaches. You do it alone in the arena and I think that ups the ante a little bit.

I think the Davis Cup has some untapped potential. It should be as prominent as the Grand Slams when it takes place. If you put it together with Fed Cup for an organized, nationalistic team competition taking place in a central location for two weeks, I think that would be beneficial from a fan interest stand point, from a media stand point and from a television stand point.

When your four biggest tournaments all operate relatively independently, and the ATP and WTA tour operate independently, and you have Davis Cup and Fed Cup that operate independently, it makes it a tough message.

Us going out there and performing our best. That's how I define success. I'm not going to define it for us by the wins and the losses as much as by the effort and how we handle ourselves.

I think there's no reason the Davis Cup couldn't be as powerful and popular and profitable as any of the four majors are today, given some changes.

The first thing I would do is create one office that controlled all of pro tennis so you had one central voice that spoke for tennis. Central governance is something that's really held the sport back and will continue to do so.

One of Nadal’s strengths is that he’s so humble, that he’s surprised at what he has achieved, and that he has never bought into his greatness.
